- Add: 1/2 + 2/3 = 1 · 3/2 · 3 + 2 · 2/3 · 2 = 3/6 + 4/6 = 3 + 4/6 = 7/6
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 3 = 6. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - one half plus two thirds = seven sixths. - Add: the result of step No. 1 + 5/4 = 7/6 + 5/4 = 7 · 2/6 · 2 + 5 · 3/4 · 3 = 14/12 + 15/12 = 14 + 15/12 = 29/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 4 = 24. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - seven sixths plus five quarters = twenty-nine twelfths.

The sum of two numbers is 1. Identify this two numbers if you know that the half of first is equal to the third of second number. Integer add to fraction 7 is added to the sum of 4/5 and 6/7; Stones in aquarium In an aquarium with a length of 2 m, 1.5 m wide and 2.5 m deep, the water is up to three-quarters of the depth. 1) multiply the numerator of fraction 1 by the denominator of the fraction 2. And get the same value when we. 2) multiply the denominator of fraction 1 by the numerator of the fraction 2. This process is called cross-multiplication. Here are some examples: 2/12 is equivalent to 1/6 because 2 x 6 = 12 x 1 = 12; 3/18 is equivalent to 1/6 because. 1.6 centimeters equal 0. Inches (1.6cm = 0.in). Converting 1.6 cm to in is easy. Simply use our calculator above, or apply the formula to change the length 1.6 cm to in.
The fraction 12 10 is equal to 6 5 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (6 5. Tap forms 5 3 7 download free.

3/r-1 = 6/r+2
Hi..
Let me first warn you that I CANNOT get the denominators of this problem to go underneath the numerators. It looks good on my answer page but when I click 'preview your answer' the denominators are ALL over the place. Grrrrr.
I think the weirdly placed denominators make this explanation hard to understand but you give this a go and see if you understand things. If it is too hard to see, maybe this website will let you instant message me or email me. If so, then I will send you the solution via email. I'm very sorry the denominators are SO scattered.
See what you think of the explanations below but it might help if you write down my answer on paper, so that you can move the number to rest more closely under their proper numerators. :-)
Ok then...
Let's start with your first problem. A quick way to do this work is to cross multiply. Here's what I mean:
__3___ = __6___
r - 1 r + 2
Ok, so you can cross multiply:
3(r + 2) = 6(r - 1) (cross multiply)
3r + 6 = 6r - 6 (use the distributive property)
Now you will have to put the 'r' variables on the left side of the equal sign and numbers without variables on the right side of the equal sign. To get 6r from the right side to the left, you can subtract 6r from the right side. If you subtract it from the right, you must subtract it from the left...
To get 6 from the left side to the right, you can subtract it from the left. If you subtract it from the left, you must subtract it on the right...
So now you have:
3r - 6r = -6 - 6 This becomes.....
- 3r = -12
Now to solve for 'r' you will have to divide by -3. Why? Well, -3r is really saying: -3 times r. The -3 and the r are actually being multiplied together so to isolate the 'r' you have to sort of 'undo' the multiplication. What is the opposite of multiplication? It's DIVISION. Soooo, you must divide by -3 on both sides. SO you have:
- 3r = -12
r = 4 (-12 divided by -3 is a positive 4)
Now you know 'r' equals 4. If we 'plug' 4 back into the original equation, we can see the answer is correct. Check this out:
__3___ = __6___ (original equation)
r - 1 r + 2
__3___ = __6___ (substitute '4' in for 'r'
4 - 1 4 + 2
__3___ = __6___ (do the math in the denominator area)
3 6
1 = 1 (3/3 equals 1 and 6/6 also equals 1, so our
solution that r = 4 is correct!) :-)
Now to your 2nd problem.....
4/2x-5 = 24/2x
___4___ = __24___
2x – 5 2x
Let's cross multiply again:
4(2x) = 24(2x - 5)
8x = 48x - 120
8x - 48x = - 120
-40x = - 120
(divide both sides by -40)
x = 3
Now let's 'plug' 3 in where we had the variable 'x' in the original equation to see if we are correct.
___4___ = __24___ (original equation)
2x – 5 2x
___4___ = __24___ (substituted 3 for 'x')
2(3) – 5 2(3)
___4___ = __24___
6 - 5 6
___4___ = __24___
1 6
4 = 4
SO once again we have found the correct answer. Yay for us! :-)
I hope this helps. :-)

Multiply each side of equation by the LCD, (r - 1)(r + 2)
This gives us: 3(r + 2) = 6(r - 1)
3r + 6 = 6r - 6
-3r = - 12
r = 4
Checking
= = , or 1 = 1 (TRUE)
NOW, YOU SHOULD BE ABLE TO DO THE OTHER ONE.
