Answer: 145
Step-by-step explanation:
Given:
58 = 40%(x)
Step 1: Turn 40% into a decimal and divide it to the other side
When turning a percentage into a decimal, the decimal point has to be moved two places to the left. This means that 40% will be turned into 0.4.
58 = 0.4(x)
Divide 0.4 over to the other side.
58/0.4 = 0.4/0.4(x)
0.4 is the same as 4/10. This means that 58/1 is divided by 4/10. When dividing a number by a fraction, you invert the fraction and multiply it by the number.
58/1 * 10/4 = 580/4 = 145
145 = x
This is your answer
