Answer:
8.75 hours
Step-by-step explanation:
We can use ratios to solve. Put the pages over the time and set them equal.
4 pages 7 pages
------------- = ---------------
5 hours x hours
Using cross products
4 * x = 5 *7
4x =35
Divide by 4 on each side
4x/4 = 35/4
x =8.75 hours
Answer:
They can make six salsa batches
Step-by-step explanation:
Here, we are told that each salsa batch require 1/4 of a cup of red onions and they have 1 1/2 cups, we want to know the number of batches of salsa that can be made
Mathematically, that would be 1 1/2 divided by 1/4
That is;
3/2 divided by 1/4
Hence;
3/2 * 4/1 = 12/2 = 6
They can make six batches of salsa
Answer:
cups of carrot.
Step-by-step explanation:
Let's set up proportional equation.
6 people need 2 cups of carrots
Let 16 people need x cups of carrots.
We could form ratio for number of people to cups of carrot used as
6:2
16:x
So, proportional equation would be
Cross multiply
32=6 x
Divide both sides by 6.
x=
Divide to get mixed number
x=5
Simplify the fraction
x= cups of carrot.
