Ratios & Proportions Example 2
James has quite a bit of free time each day. He often spends 4 hours on the computer and the other 2 hours playing basketball. What is his ratio of basketball to computer time? What proportion of his free time is spent on basketball?
To answer the first question, compare the number of basketball (jamming) hours (2) to the number of computer hours (4).
That’s 2:4. This ratio can be reduced to 1:2, by dividing each by 2.
For the second question, compare jamming hours (2) to the total free time (). You could write this proportion like a fraction:
, then reduce it to by dividing the numerator and denominator by 2.
