Multiply both sides by 16
x = (40/64) * 16
x = 40 * (16/64)
x = 40 * (1/4)
x = 10

x/16=40/64
Multiplying both sides by 16
x= 16*40/64
or x=640/64=10

Proportional Problem
x/16 = 40/64
The means: 40(16)
The extremes: 64x
The equation
64x = 40(16)
64x = 640
Divide both sides of the equation by 64
64x / 64 = 640 / 64
x = 640/64
x = 10
- - - - - -
Check
x/16 = 40/64
10/16 = 40/64
Simplify
5/8 = 5/8

x / 16 = 40 / 64.
You can cross-multiply (multiply one side's numerator by the other side's denominator, and vice-versa) to get:
64 * x = 16 * 40.
64x = 640.
x = 10.
