Question

Ethan ran 3/4 miles. Megan ran 7/8 miles. How much further did Megan run? Answer in simplest form.​

Answer 1

2/16 or 0.625

Explanation:

Find a common denominator for the two fractions. It will be 16. 3/4=12/16

7/8=14/16 or you can do it in decimal form. 3/4=.25 and 7/8= .875

.875-.25=.0.625

Answer 2

`\large\boxed{(1)/(8)\ \text{miles}}`

We need to subtract Ethan's distance from Megan's. First, we need to have a common denominator in the fractions.

Multiply both the numerator and the denominator in
`(3)/(4)` by
`2` to get
`(6)/(8)`, which is equivalent. Now, both numbers have a denominator of
`8` and can be subtracted.

Now, simply subtract the numerators, leaving the denominator alone.

`(7)/(8)-(6)/(8)=(7-6)/(8)=\boxed{(1)/(8)}`
