Answer 1

3:7

Explanation:

Given:

• There are 28 students in a class
• 16 of the students are girls.

To Find:

• What proportion of the students are boys.

Formula used:

• No. of boys = Total students - No. of girls

Using the formula, we have

No. of boys = 28 - 16 = 12

Proportion of boys = 12/28 = 3/7

So, proportion of boys = 3:7.
