Answer 2

It looks like you've provided two ratios: 7:5 and 5:10.

7:5 can also be written as 7/5. This ratio means that for every 7 units of one thing, there are 5 units of another thing. Without more context, it's difficult to say exactly what the ratio is referring to.

5:10 can be simplified by dividing both sides by 5, giving us 1:2. This ratio means that for every 1 unit of one thing, there are 2 units of another thing. Again, without more context it's difficult to say exactly what the ratio is referring to.
