Question

Pamela ran 7/10 mile on Tuesday and 3/8 mile on Thursday. How much farther did she run on Tuesday?

1. 2 miles
2. 13/40 miles
3. 3/40 miles
4. 5/9 miles

Answer 1

Option 2.

13/40 miles

Explanation:

Tuesday

Pamela ran 7/10 mile = 0.7 miles

Thursday

Pamela ran 3/8 mile = 0.375 miles

If we subtract both quantities we can find how much farther she ran

0.7 miles - 0.375 miles = 0.325 = 13/40 miles
