26/57 = 849/5× (×=372.25)

Question

Prove true

Answer 1

This type of equation is called a proportion, an equality of two ratios or fractions. If a proportion is true, then the product of the "means" (57 and 849 in this case) is equal to the product of the "extremes" (26 and 5x in this case).

 

Checking: If 26/57 = 849/5x, then (26)(5x) = (849)(57) or x = (849)(57)/(26)(5) ≅ 372.25.

 

So the proportion is true.
