7. Find the value of:
a) The number when 40% of the number is 10

Answers

Step 1) Set up a proportion

Proportion: percent / 100 = x / number

In context of the problem, the proportion is: 40 / 100 = 10 / number

Step 2) Cross-multiply and solve

100 x 10 = 40 x N

1000 = 40N

N = 25

Answer: The number is 25

Answer:

25

Step-by-step explanation:

Lettheunknown number bex

40 \% * x = 10 \n (40x)/(100) = (10)/(1)

CrossMultiply

40x = 100 * 10 \n 40x = 1000

Divide both sides of the equation by40

(40x)/(40) = (1000)/(40)

Simplify

x = 25
