Jackson’s age was 2/5 of the age he will be 20 years from now 7 years ago. How old is Jackson now?

bonufazy [111]

<h3>The present age of Jackson is 25 years old</h3>

<em><u>Solution:</u></em>

Let the present age of Jackson be "x"

Therefore

Jackson's age 7 years ago = x - 7

And, Jackson's age after 20 years = x + 20

From given question,

Jackson’s age was 2/5 of the age he will be 20 years from now 7 years ago

$\frac{2}{5} \times (x + 20) = x - 7\\\\2(x + 20) = 5(x - 7)\\\\2x + 40 = 5x - 35\\\\5x - 2x = 40 +35\\\\3x = 75\\\\Divide\ both\ sides\ by\ 3\\\\x = 25$

Thus present age of Jackson is 25 years old

How to subtract unlike faction

zvonat [6]

First, multiply the individual fractions in order to get the same denominators. Then, add the numerators and don't change the denominator.

For example:
1/2-1/4

You have to multiple the first fraction by two so both fractions have a denominator of 4.

2/4-1/4
=1/4
