Question

if you subtract 1/8 from a number and multiply the result by 1/4, you get 1/10, what is the number

Answer 1

Step-by-step explanation:

Let the number be x

A. T . Q , w/ g

1/4 (x- 1/8) = 1/10

1/4(8x-1/8) = 1/10

8x-1 / 32 = 1/ 10

8x= 1/10+ 1/32

8x = 1×16 + 1×5 / 160

8x= 16 + 5 / 160

8x = 21/ 160

x = 21/ 160 × 8/ 1

x= 21/ 20

Answer 2

Let the number be x

According to the question

$(x - \frac{1}{8} ) \times \frac{1}{4} = \frac{1}{10} \\ ( \frac{8x - 1}{8}) \times \frac{1}{4} = \frac{1}{10} \\ \frac{8x - 1}{32} = \frac{1}{10} \\ 80x - 10 = 32 \\80x = 32 + 10 \\ 80x = 42 \\ x = \frac{42}{80} \\ x = \frac{21}{40}$
