A survey revealed that 4 out of 5 people prefer vanilla ice cream to chocolate. In a class of 30 how many students are likely to prefer chocolate ice cream?

1/5 = x/30
Cross multiply and solve:
5x = 30
x = ?

I'm pretty sure it's 24.
Because you figure 30/5=6 So then just take the 6 and times it by the 4. 4*6=24

Nope. 24 prefer vanilla.
The question asks about preferences for chocolate.
