Hi!
10.
This question is basically asking you, 10 is 40% of what number?
10 × 100 / 40 = 25
Fred must do 25 math problems.
12.
Bed & Bath = 40%
Clothing = 0.625 = 62.5%
Appliances = 20%
Electronics = 0.25 = 25%
Least to Greatest: Appliances (20%), Electronics (25%), Bed & Bath (40%), Clothing (62.5%).
The answer would be 12/54 (twelve fifty fourths) but if you simplify it you would get 2/9 (two ninths).
Black is black.
Blue is blue.
Red is red.
