13) Ok so if you run 1 mile in 8 minutes, the ratio will be 1:8. So you do
8(5) = 40 minutes
You take 40 minutes to run 5 miles.
( because of every 8 minutes you run one mile so you will multiply the amount of minutes(8) by the amount of miles(5).)
14) The ratio for this one is 1:12.5.
You work backwards to find this answer
400/32 (divide 32 into 400)
In one hour you earn 12.5.
To be sure check your answer like this
12.5*32= 400
15) For this one I’m not too sure (someone correct me if I’m wrong) I think the 24 oz would be a better buy.
The 24 oz cost $1.40 while the 32 oz cost $3.09 thats a $1.69 difference in price. If you wanted to get three loafs but you only have 5 dollars. Your best choice would be the 24oz because
$1.40*3 = $4.20
$3.09*3 = $9.27
In this case you will get three loafs for just under 5 dollars making the 24 oz a better buy.
( you multiply the price of one loaf by the amount of loafs you want)
Hope this helped :)
