  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
