What is the answer cause i have having trouble knowing if it was right

How to find each one: So first, if you have a fraction, (you probably want to simplify the ones you've put in by dividing both sides by the same number, for example, 45/100, both sides by 5, 9/20)

So if you have a fraction: 

You can find the ratio by just putting the numerator on the left, n:, and the denominator on the right. n:d

For example, with 5/9, 5:9.

For decimal, you can just divide. For example, 4/5, 0.8. 

Percent, just change the decimal to have a hundredths place, with 0.8, 0.80, and then just take those two digits, or 80%.

So basically, for ratio, you can do it if you have the fraction.

For the column fraction, if you know basic fractions, you can also convert from those, and also from the ratios.

For decimal, if you know percent or fraction, you should be able to find it.

Percent, fraction or decimal should work.

I'll do a row to explain, it's kind of confusing, sorry:

So if you have 9:20, you can convert that to the fraction, 9/20.

Then you can find the decimal, 9/20 = 0.45

Percent would therefore be 45%.

Hope this helped :)
