This is a proportion. You need to be able to find the missing value based on the information they've provided you with.
Here's the best way to solve ⇒
2/3 = x/48
Cross multiply them. ⇔ 2*48 = 3x
96 = 3x
x = 32
the missing value is 32
Cross multiplication!
Because it is a proportion
\(\frac{2}{3}\) = \(\frac{?}{48}\)
2 × 48 = 3 × ?
96 = 3 × ?
Divide by 3 on both sides to isolate the unknown number
\(\frac{96}{3}\) = \(\frac{3 * ?}{3}\)
3 and 3 cancels out
32 = ?
The unknown number is 32
