Page 61 Question 11
Shannon buys 12 granola bars for $9.96.
a) Determine the price per bar. Give your answer in dollars and cents.
b) Explain whether your answer in part a)is a ratio or a rate.
It's a rate because we're comparing 2 things with different units of measurement
Ratio-a way to compare 2 quantities, sort of like a fraction but only sideways example: (a word ratio) pears to apples (a regular number ratio) 1:3
there are many ways to compare different numbers in a ratio (part to part to part, part to whole, etc.)
Rate- when you compare 2 things in different units. example: $12/per hour
Coin Math Question:
