Respuesta :

Percentage is expressed in terms of 100

For the first part,

70/100 shows 70% as a ratio

For the second part,

if the whole is represented by x, then the ratio, 84/x compares 84 to the whole, x

To solve for x, it becomes

70/100 = 84/x

by cross multiplying, it becomes

70x = 84 * 100 = 8400

x = 8400/70

x = 100 l
