\(\frac{x}{2.4} = \frac{3}{8}\)

For proportions and to find x we have to cross multiply
8 × (x) = 3 × 2.4

8x = 7.2
Divide by 8 to isolate x

\(\frac{8x}{8} = \frac{7.2}{8}\)
8 and 8 cancels out

x = 0.9

you have to cross multiply to get x on its own
1) Multiply everything by 2.4 
\(x= \frac{3 X 2.4}{8}\)
2) Then simplify the fraction
 \(x= \frac{7.2}{8}\)
3) You can either leave the answer as a fraction or you put it as a decimal
x=0.9
