Question

The day before an exam, Jacob spent 2 1/5

hours studying in the morning and 3 3/4 hours
studying in the afternoon. How many hours
did Jacob spend studying that day?

Answer 1

5 19/20 or 5.95

Explanation:

You can add these numbers as decimal numbers or as mixed numbers.

Decimal

2.2 +3.75 = 5.95 . . . hours spent studying

Mixed Numbers

(2 1/5) +(3 3/4) = (2 4/20) +(3 15/20) = (2 +3) +(4/20 +15/20)

= 5 19/20 . . . hours spent studying
