Question

Jonah runs 3/5 mile on Sunday and 7/10 mile on Monday . He uses the model to find that he ran a total of 1 mile. What mistake does Jonah make? I NEED ANSWERS ASAP

Answer 1

His mistake was adding the numerators together without converting the fractions to have a common denominator

Explanation:

3/5 + 7/10

convert fractions to have common denominator

6/10 + 7/10 = 13/10

convert improper fraction to mixed number

1 3/10

He ran a total of 1.3 miles

Answer 2

see below

Explanation:

3/5 + 7/10

We did not get a common denominator

He added the numerators and got 10/10 = 1

He should get a common denominator

3/5 * 2/2 + 7/10

6/10 + 7/10

13/10

10/10 + 3/10

1 3/10 miles
