SAMPLE QUESTION
SAMPLE QUESTION
In a survey, the ratio of various fruit preferences was recorded. The ratio was 5 : 4 (apples : watermelon) when simplified.
If there were 80 students who preferred apples, how many likes watermelon?
APPLES : WATERMELON
5 : 4
80 : X
Ask yoursel - what did you do to the 5 to get to 40? You multiplied by 16.
WHAT YOU DO TO ONE SIDE, YOU DO TO THE OTHER!
So 4 x 16 = 64.
Therefore 64 students liked watermelon.
