How to make equivalent ratios

Equivalent ratios are the same as fractions written sideways. It's written differently but means the same thing. For example, 2 : 4 is the same as 2 : 4. Whatever you do on one side, you do it on the other side.
Questions
1. True or False. A part to part ratio compares one part of a group to the whole group.
2. simplify 148 : 111.
3. If there are 3 stars and 1 moon. What should I write if I'm comparing moon to stars?Explain why.

1. True or False. A part to part ratio compares one part of a group to the whole group.

False, because a part to part is a ratio that compares one part of a group to another part.

2. simplify 148 : 111.
4:3

148 / 37 = 4
111 / 37 = 3

3. If there are 3 stars and 1 moon. What should I write if I'm comparing moon to stars?Explain why.

moon : stars
1:3

Because, in the question you mention moon first and then you put stars. ( moon : stars )

Question 1 - False your talking about a part to whole ratio and a part to part ratioe compares two parts of a group.

Question 2 - You can't because the number 111 dosent have any factors but 1 and itself.

Question 3 - you said moon to stars so its moon:stars , 1:3
