When a number is decreased by 79% the result is 13 what is the original number to the nearest tenth
ASHA 777 [7]

Answer:

The number  is 61.9

Step-by-step explanation:

Let

x ----> the original number

Remember that

100\%-79\%=21\%=\frac{21}{100}

we know that

The original number multiplied by the fraction 21/100 must be equal to the number 13

so

The linear equation that model this situation is

\frac{21}{100}x=13

solve for x

Multiply by 100 both sides

21x=1,300

Divide by 21 both sides

x=\frac{1,300}{21}=61.9
