Question

) Reid is taking piano and trumpet lessons. He likes the piano more, and last month practiced the piano 5 hours for every 3 hours he practiced the trumpet. )) Pick the diagram that models the ratio in the story. )) If Reid spent 4 more hours practicing the piano than the trumpet last month, how many hours did he spend practicing the piano?

Answer 1

The diagram that models the ratio in the story is:

Piano: Trumpet
5:3

If Reid spent 4 more hours practicing the piano than the trumpet last month, it means that the ratio now becomes:

Piano: Trumpet
5+4:3

Simplifying this ratio, we get:

Piano: Trumpet
9:3

Since the ratio is 9:3, and the total practice hours for last month is 12 hours (5+3=8), we can determine that Reid spent 9 hours practicing the piano.
