Answer 1

I only know these ones tho...

1. 60:13 (You arrange it to the order the question asked in this case they asked for "the ratio of students to teachers" so I did that)

2. 16:56 (You are supposed to add them like this to get the ratio of students 40 + 16 = 56)

3. 11:16 (You arrange them in the order that the question asked for your example was "What is the ratio of calico kittens to non-calico kittens" so I arranged them like that)

4. 10:17 (You are supposed to add them like this to get the ratio of attendees 7 + 10 = 17)

5. 2:7 (What we do is that because they told us there are 2 brindle puppies and we know the number of puppies is 9 so we minus the 2 brindle puppies from 9. To find the amount of non-bridle puppies we do this 9 - 2 = 7)

6. 28:40 (You are supposed to add them like this to get the ratio of attendees to teenagers 28 + 12 = 40)

7. 11:33 (You are supposed to add them like this to get the ratio of total cakes 22 + 11 = 33)

8. 110:19 (What we do is that because they told us there are 110 students and we know the number of people is 129 so we minus the 110 students from 129 to find the ratio of students to teachers we do this 129 - 110 = 19)

9. I don't know.

10. I don't know.

Explanation:

For 1-8, they are ratios. Ratios can be expressed in many two major ways. Fractions, and the answer i put. Ratio is like division. Therefore, you divide it by something.

Let’s bring question 8 for example,

It says: There are 110 students on a bus filled with 129 people. What is the ratio of students to teachers?

The given fact is that there is 110 students and 129 in total. It means that there is 19 adults, since 129-110 is equal to 19. Then, it’s looking for the ratio of students to teacher. The answer would be 110:19, 110/19, or 110 divided by 19

For question 9, it asks how much oranges Lisa will use if she serves 800 people.

It takes 9/40 oranges per servings. To solve this, we need to multiply 9/40 by 800, which is equal to 180(9/40*800=7200/40=180)

For question 10, we have to find how much it costs for a single ring.

if 5 rings cost $1, it means that it costs $0.2 per ring, since 1/5 is equal to 0.2. Then, we have to multiply it by 50. 0.2 time 50 is equal to 10.

I hoped this helped
