Question

Two thirds of a number is 3 1/2 more than 3/8 of the number find the number

Answer 1

let the number be x.

(2/3)x = 3 1/2 + (3/8)x

(2/3)x - (3/8)x = 3 1/2

(8*2 - 3*3)/(8*3) x = 7/2

(16 - 9)/24 x = 7/2

(7/24)x = 7/2

7x/24 = 7/2 Divide both sides by 7

x/24 = 1/2

x = 24*1/2

x = 12

The number is 12.
