Answer:
The answer is 1. 64 and 2. 60
Step-by-step explanation:
Question 7. 75% of what number is 48?
Number = x
75%x = 48
3x/4 = 48 (75% = 3/4)
3x = 192 (Multiplying by 4 at both sides of the equation)
x = 64 (Dividing by 3 at both sides of the equation)
Part 75 Whole 48 Part 100 Whole 64
Question 8. 120% of what number is 72?
Number = x
120%x = 72
12x/10 = 72 (120% = 12/10)
12x = 720 (Multiplying by 10 at both sides of the equation)
x = 60 (Dividing by 12 at both sides of the equation)
Part 120 Whole 72 Part 100 Whole 60
