What is the answer for 2/4 = (?) % x 2/5 ?

Question

please show me the solution/formula.As soon as possible please..thanks.

Answer 1

I turned all the numbers into decimals. So

2/4 is equal to 0.5  and

2/5 is 0.4

so    0.4= ? x 0.5

or    0.5 / 0.4 = 1.25

Then I changed the answer into a percentage and two fractions like the question required

2/4= 125% x 2/5

I haven't done maths for a long time so I may be way off base!

Answer 2

Your question ended up in the wrong section and you seriously need to learn how to do your own homework.

Replace (?)% with x/100 and do it the algebra way i.e. find the value of x.
