37,5%

X=(18 × 100)/48

X=37,5%

Answer 2

Answer: 38% of the class is left handed.

Step-by-step explanation:

The first step is to set up the equation:

18/48 = x/100

The second step is to set solve the equation:

18/48 = x/100

Cross multiply:

18 × 100 = 1800

48 × x = 48x

So,

1800 = 48x

Then divide 48 on each side to isolate the variable:

1800/48 = 48x/48

37.5 = x

x = 37.5

Since you can not have half a person, you must round the percentage from 37.5% ⇒ 38%.
