Question 1 options:<br><br> 3<br><br><br> 8<br><br><br> 12<br><br><br> 2.5
rewona [7]

Answer:

2.5

Step-by-step explanation:

(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)

\frac{2}{x}=\frac{12}{15}

Cross multiply

12x=30

Divide

x=2.5

This is just one way to do the problem. An easier way is to simplify the fractions.

\frac{2}{x}=\frac{4}{5}

You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5
