Question

if 7:8 =x% , what is the value of x

Answer 1

We will follow basic rules of ratio and proportion to arrive at our final answer.

$\large{\boxed{\textbf{\underline{Solution:}}}}$

7 : 8 = x %

We know that a ratio can also be written in fraction so,

7 / 8 = x %

We know that the percent of any number is equal to the number by 100 so,

7 / 8 = x / 100

Taking 100 from RHS to LHS,

( 7 / 8 ) * 100 = x

Exchanging LHS and RHS as well as solving new RHS,

x = 700 / 8

Performing simple division,

x = 85

Therefore,

$\large{\textbf{\underline{x=85}}}$
