Answer 1

Explanation:

Let the number to be found be x

a).

68 is what percent of 80 is written as

`(x)/(100) * 80 = 68`

Multiply both sides by 100

We have

80x = 6800

Divide both sides by 80

we have the answer as

x = 85

Therefore the percentage is 85%

b).

Let the number be x

88.83 is 423% of what is written as

`(423)/(100) x = 88.83`

Multiply through by 100

We have

423x = 8883

Divide both sides by 423

We have the answer as

x = 21

The number is 21

c).

Let the number be x

36.8% of what number is 28.52 is written as

`(36.8)/(100) x = 28.52`

Multiply through 100

We have

36.8x = 2852

Divide both sides by 36.8

We have the answer as

x = 77.5

The number is 77.5

d).

What number is 95% of 40 is written as

`(95)/(100) * 40`

We have the final answer as

38
