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.
oh, ok! wow..way to not read directions. my bad.
I GUESS IT'S 6 AS 4/5 PREFER VANILLA.THEN,4/5*30=24 AND 30 - 24=6
