    Step-by-step explanation:

    3+5=8

    40÷8=5

    5 is 1 part of 40

    5×3=15

    5×5=25

    Checking

    15 + 25 = 40

    15÷5=3

    25÷5=5

    3:5

    There are 15 boys and 25 girls in the class.

    15 boys, 25 girls

    Step-by-step explanation:

    1. Add the ratios

    3 + 5 = 8

    2. Divide the total number by the total ratio

    40 ÷ 8 = 5

    3. Multiply the answer in step 2 by the ratios

    5 × 3 = 15

    5 × 5 = 25

    Therefore, there are 15 boys and 25 girls in the class.
