Answer:
Dogs: 44.44 Cats: 55.556
Step-by-step explanation:
*this is <em>only </em>if you are allowed to use a calculator*
1. You have to add the total of the cats and dogs
Why? Here, let me put it this way. You have a test with two sections: math and science. If there are 2 Maths Questions and 2 Science questions, what percent of the test are math questions? You would not say 2/2 and say 100. You would say 2/4 because it is obvious. You do the same in this case but it is not as noticeable because you are dealing with bigger numbers.
15 + 12 = <u>27</u>.
2. Solve
<u>a. </u>There are 15 dogs and 12 cats that makes up 27 pets total.
So you have to do 12/27 for cats,
15/27 for dogs. The fractions equal one and It shows you how much of one is there compared to the total.
<u>b. </u><u><em>Simplify</em></u>
You can simplify these fractions:
for 12/27, divide the numerator and the denominator by 3.
You get 4/9
Divide 15/27 for dogs by 3 as well to get 5/9.
5+4 is 9, which means that I am doing the math correctly.
According to the calculator, 5/9 is 55.556, and 4/9 is 44.444
They should be accurate because there are more dogs than cats and the percentage for dogs are higher. Hence, this is correct.
Cats = 4/9 = 44.444%
Dogs = 5/9 = 55.556%
Hope this helps :)
