Question

Find the value of x, given 36, 90, 90, x are in proportion​

Answer 1

x = 225

Step-by-step explanation:

36 : 90 : : 90 : x

= 36 / 90 = 90 / x

= 2 / 5 = 90 / x ( Cross Multiplication )

= 2x = 90 × 5

= 2x = 450

= x = 450 / 2

= x = 225

x = 225

then

36 : 90 : : 90 : 225

= 36 / 90 = 90 / 225

= 2 / 5 = 2 / 5 ( Cross Multiplication )

= 2 × 5 = 2 × 5

= 10 = 10

★ The LHS and RHS is equal.

★ So the x = 225
