Question

Add or subtract. use the least common multiple as the denominator what is 5/8-5/25

Answer 1

Answer:
17/40
Explanation:

First, we need to find the common denominator of 5/8 and 5/25, which is 200.

5 x 25/ 8 x 25 - 5 x 8 / 25 x 8
= 125/200 - 40/200

Next, subtract both fractions:

85/200 is our difference.

Let's simplify, divide both sides of the fraction by 5:

85 / 5 and 200 / 5
= 17/40

17/40 is your simplified answer.

Answer 2

17/40

Explanation:

First let's find the least common denominator. The denominators are 8 and 25 so we need to find the least common multiple of 8 and 25.

8=2*2*2

25=5*5

Since they share no common factors the least common multiple of 8 and 25 is 8*25 which is 200.

Now we convert the fractions:

5/8*25/25=125/200

5/25*8/8=40/200

Then we subtract:

125/200-40/200=85/200

Now we simplify it:

17/40
