Question

If 7:8 = x% then what's the place of x ?

Answer 1

Answer:

          1

x = 87 _

          2

Step-by-step explanation:

7 : 8 = x %

x % = 7 : 8

x / 100 = 7 / 8

x × 8 = 7 × 100

Divide 4 on both sides,

x × ( 8 / 4 ) = 7 × ( 100 / 4 )

x × 2 = 7 × 25

x = 175 / 2

          1

x = 87 _

          2
