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

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
