Question

HOW DO U DO THIS PROBLEM

Answer 1

OK since 2/5 is being multiplied by x we have to divide both sides by 2/5.

2/5 times X divided by 2/5 is x 10 divided by 2/5 is 25

X=25

Answer 2

So what you had done wrong on this question is that you didn't multiply by the reciprocal of 2/5, which is 5/2, not 5/1.

The steps to the solution:

Multiply 5/2 on each side:
`(5)/(2) * (2)/(5)x= (10)/(1) * (5)/(2)`

Then just simplify your answer:
`x= (50)/(2) =25`
