Answer 1

Answer:

d.187

Step-by-step explanation:

First, you will want to write out what you know

The ratio is 1:3.

There are 561 monkeys

apes are the 1 and monkeys are the 3

Then do the math

so you divide 561 by 3. (I think I wrote that right...)

561/3 = 187

d. 187

Answer 2

Answer:

187 [D]

Step-by-step explanation:

When a ratio is 1 to 3, it means for every 3 __ there is 1 __

(the blanks are given from the order of the statement)

So, for every 1 ape, there are 3 monkeys

We can rewrite this as :

3 monkeys : 1 ape

[because we know how many monkeys]

If there are 561 mokeys, we want to find how many "3 monkeys" make up that total number

561 ÷ 3 = 187

So, because there are 187 groups of 3 monkeys, we know that there should be 187 apes.

This makes D, 187, the correct answer.

hope this helps!!
