### Binesi's Rate Growing Post

Page 60 question 7
The table shows the price of different-sized
packages of mixed nuts.
a) What is the unit price per 100 g for each package?

300/3=100 2.19/3=\$0.73
500/5=100 3.09/5=\$0.62
700/7=100 4.83/7=\$0.69

The 500g package costs the least per 100g.

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.
12/12=1 9.96/12=0.83
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

Definitions:
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:
If there were 370 coins in the Canadian currency jar and they were evenly divided within 5 jars, what would be the rate of coins per jar?

370/5=74 74/per jar
