Answer:
Danalya napped 1 7/20 hours.
Step-by-step 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
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
