Step-by-step explanation:
Let the number to be found be x
68 is what percent of 80 is written as
[tex] \frac{x}{100} \times 80 = 68[/tex]
Multiply both sides by 100
We have
80x = 6800
Divide both sides by 80
we have the answer as
x = 85
Let the number be x
88.83 is 423% of what is written as
[tex] \frac{423}{100} x = 88.83[/tex]
Multiply through by 100
We have
423x = 8883
Divide both sides by 423
We have the answer as
x = 21
Let the number be x
36.8% of what number is 28.52 is written as
[tex] \frac{36.8}{100} x = 28.52[/tex]
Multiply through 100
We have
36.8x = 2852
Divide both sides by 36.8
We have the answer as
x = 77.5
What number is 95% of 40 is written as
[tex] \frac{95}{100} \times 40[/tex]
We have the final answer as
