Question

(2x)/(25)=(0.4)/(0.15)

Answer 1

x = 100/3 = 33 1/3 = 33.333...

Explanation:

You want the value of x given (2x)/25 = 0.4/0.15.

Solution

Multiply both sides of the equation by the inverse of the coefficient of x:

(25/2)(2x/25) = (25/2)(0.4/0.15)

x = (25×0.4)/(2×0.15) = 10/0.3 = 100/3

The value of x is 100/3. As a mixed number, that is 33 1/3. As a decimal, it is the repeating decimal 33.33....
