Question

Miguel napped for 2 2/5 hours. Danalya napped too. Combined they napped for 3 3/4 hours

. How many hours did Danalya nap?

Answer 1

the answer is 1 7/20

to figure out how many hours danalya napped, you have to subtract 3 3/4 - 2 2/5

first, find common denominators

3 3/4 = 3 15/20
2 2/5 = 2 8/20

3 15/20 - 2 8/20 equals 1 7/20

Answer 2

Danalya napped 1 7/20 hours.

Explanation:

Rewriting our equation with parts separated

=3+3/4−2−2/5

Solving the whole number parts

3−2=1

Solving the fraction parts

3/4−2/5=?

Find the LCD of 3/4 and 2/5 and rewrite to solve with the equivalent fractions.

LCD = 20

15/20−8/20= 7/20

Combining the whole and fraction parts

1+7/20= 1 7/20
