Simple...what fun!

To solve for this type of problem...it's real simple!

I will show you the easiest and fastest way to solve...

so..you have...

[tex] \frac{2}{5} = \frac{x}{35} [/tex]

Just..CROSS MULTIPLY!!

2*35=70
and
5*x=5x

Leaving you with....

5x=70

Easy...now divide!!

[tex] \frac{5x}{5} = \frac{70}{5} [/tex]

x=14

To check your work...plug it in....

[tex] \frac{2}{5} = \frac{14}{35} [/tex]

simplify...

14/7=2

and

35/7=5

Thus, your answer.
