1/10, 18/25, 5/8 are the same as
20/200, 144/200 and 125/200, you decide
The LCD of 7/10 and 18/25 is 50.
5/8 = 25/40 7/10 = 28/40 So the second is bigger.
7/10 - 9/25 = 35/50 - 18/50 = 17/50
18 over 25 is the same as 18 divided by 25. 18 / 25 = 0.72 or 72%
The least common denominator would be 50
4/10 / 5/9 = 4/10 * 9/5 = 36/50 = 18/25
(18/63)*(25/10)*(36/100) = (2/7)*(5/2)*(9/25) = (5/7)*(9/25) = (1/7)*(9/5) = 9/35
18 over 50 can be simplified as 9 over 25.
It is: 18/25 is 72%
18/25= .72
18/25 = 72%
4/15 = 20/75 7/25 = 21/75 So, 7/25 is bigger.
