Question

If we subtract 1/2 from a number and multiply the result by 1/2 , we get 3/8 .what is the number?

Answer 1

hey bro!

ur solution is here:
________________

Let the number be X

then substract 1/2 form number

so

=> (x - 1/2)

now
multiply the result by 1/2

then

==> (X - 1/2)×1/2

we get equal to 3/8

so

==> (x-1/2)×1/2 = 3/8

==> (x-1/2) = 3×2/8

==> x-1/2 = 6/8

==> X = 6/8+1/2

==> X = 6+4/8

==> X = 10/8

==> X = 5/4 Ans

Hope it's helpful ✌✌☺
