Answer:
42 rats.
Step-by-step explanation:
since the ratio of mice to gerbils is 7:4, given that there are 32 gerbils, that means 32/4=8 gerbils; in other words, 56mice:32gerbils. Then, to find the # of rats, the ratio is 4:3, so you take the previous value of the # of mice and divide it by 4 to get 14(3)= 42
To understand this question, we need to know what it's asking and what's important and what is not important. Many people skip this step, but it is very important.
It is asking us to Find how many Rats there are.
This problem is defiantly reduced to the simplistic ratio
The next step is to Find clues
The clues are 32 Gerbils, 7:4 and 4:3
Now i like to make a chart but you may skip this step if you want
Gerbils=32
Mice=??
Rats=??
First, we have to find the numbers of Mice.
(Reducing Ratios divide them by a number like 2:4=1:2)
If you have 32 Gerbils and you reduced it to 4, what did you dived?
32/4=8
So, you multiply 7x8=56
There is 56 Mice.
Our table looks like this
Gerbils=32
Mice=56
Rats=??
Now we use the ratio 4:3 to find the numbers of Rats
If there are 56 mice, and it is reduced to 4, we have to do 56/4 to find out what we have to multiply 3 by to get the total numbers of rats (Inverse Operation) by. We get 14.
So now we do 3x14 in which we get 42.
Our chart now looks like this
Gerbils=32
Mice=56
Rats=42
I Hope this helped if you have any questions just tell me
