Answer: a/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c

Tell whether the 2 rates form a proportion:a) 28 points in 3 games, 112 points in 12 games
b) 32 notes in 4 measures, 12 notes in 2 measures
Show work if you can please :)

Answers

Final answer:

The rates 28 points in 3 games and 112 points in 12 games form a proportion, while the rates 32 notes in 4 measures and 12 notes in 2 measures do not form a proportion.

Explanation:

To determine whether the given rates form a proportion, we need to check if the ratios are equivalent. a) We'll start with 28 points in 3 games vs 112 points in 12 games. The ratio 28/3 equals approximately 9.33, and the ratio 112/12 also equals approximately 9.33. Since these ratios are equal, these rates do form a proportion. b) Moving to 32 notes in 4 measures vs 12 notes in 2 measures. The ratio 32/4 equals 8, and the ratio 12/2 equals 6. Since these ratios are not equal, these rates do not form a proportion.
