Answer:

x = 94.2

Step-by-step explanation:

Let x represent the number

x - 4.5%x = 90

x - 4.5/100x = 90

x - 0.045x = 90

0.955x = 90

Divide both sides by 0.955(the coefficient of )

x = 90/0.955

x = 94.2

Write each Percent as a decimal and as a mixed number or fraction in simplest form

sveticcg [70]

$p\%=\dfrac{p}{100}\\\\225\%=\dfrac{225}{100}=2\dfrac{25}{100}=2.25=2\dfrac{1}{4}\\\\550\%=\dfrac{550}{100}=\dfrac{55}{10}=5\dfrac{5}{10}=5.5=5\dfrac{1}{2}\\\\0.8\%=\dfrac{0.8}{100}=\dfrac{0.8\cdot10}{100\cdot10}=\dfrac{8}{1,000}=0.008=\dfrac{1}{125}\\\\0.06\%=\dfrac{0.06}{100}=\dfrac{0.06\cdot100}{100\cdot100}=\dfrac{6}{10,000}=0.0006=\dfrac{3}{5,000}$
