The product of a number and ten is twelve more than the product of the number and five-eighths.
ra1l [238]
Let the unknown number be x.

Given,

10 * x = 12 +  \frac{5}{8}  * x

10x = 12 +  \frac{5x}{8}

10x -  \frac{5x}{8} = 12

\frac{(10x*8)-5x}{8} = 12

80x-5x =12*8

75x = 96

x = \frac{96}{75} = 1.28

Hence, the number is 1.28
