    30 boys

    Step-by-step explanation:

    Girls:Boys=Girls:Boys

    5:6=25:x

    Means = (6)(25)

    Extremes = (5)(x)

    5x=150

    5x/5=150/5

    x=30

    There are 30 boys in the class.

    The given ratio of the problem is 5:6, from girls to boys. Since there are 25 girls in class, we put it as 25:x. Let x be the number of boys in class.

    5:6 = 25:x (Cross Multiply)

    5x = 150 (Divide both sides by 5)

    x = 30

    Or, you could use:

    If there is 5:6 ratio, and there are 25 girls, 25/5 = 5 × 6 = 30, which means

    There are 30 boys in class

    answer:

    30 boys

    Step-by-step explanation:

    Since

    5 : 6 = 25 : X

    Then we know

    6/5 = X/25

    Multiplying both sides by 25 cancels on the right

    25 × (6/5) = (X/25) × 25

    25 × (6/5) = X

    Then solving for X

    X = 25 × (6/5)

    X = 30

    Therefore

    5 : 6 = 25 : 30
