3.5 BIM Review Unit Rate

3.5 BIM Review Unit Rate

We are covering the top 3 most difficult problems from the 3.3 HW on BIM.

#6

• We are trying to find the cost of each egg, which is our unit rate

• We spent $2.35 to buy 12 eggs.

• We set this problem up by taking $2.35 and dividing it by 12.

• We do this because we are trying to find cost per egg.

• We get .195

• We round this to the nearest cent, $.20

#23

• We need to read this problem carefully- it is saying servings per package

• This wording is telling us to take our servings and divide by packages.

• Our result will be 1 package to some number of servings

•  $13.5\div3=4.5$  

• Our answer will be 4.5 when we divide any of these ratios!

#24

• We are trying to find feet per year

• This means we need to take our feet and divide by year

•  $7.2\div2=3.6$  

• Our answer will be 3.6 when we divide any of those ratios!
