Is this right??

10 + 7 = 17/100 = 41.2 %

100 + 92 = 192/100 = 1.92 %

15 + 13 = 28/100 = 1.25 %

28 + 22 = 50/100 = .5%

I don't know what the addition problems are. However, I checked your percentage answers.

This is right.
192/100 = 1.92 %

The others are wrong.

Remember to divide the numerator by the denominator and then multiply by 100.

These can you write them out for me?

100 + 92 = 192/100 = 1.92 %

15 + 13 = 28/100 = 1.25 %

28 + 22 = 50/100 = .5%

I went through them and still came out with these answers? So confused now. I udnerstand what you mean, but it comes out the numerator so I thought they were right? Can you explain each?

Can't figure out why this one is wrong?

28 + 22 = 50/100 = .5%

50/100 = 50%

28/100 = ??%

17/100 = ??%

Did you divide the numerator by the denominator?

28 divided by 100 = ?

No, those calculations are incorrect. Let's go through the correct calculations step by step.

To find a percentage, you need to divide the given number by 100. Then, you multiply the result by the percentage value you want to calculate. Here's how it should be done:

1. 10 + 7 = 17
To convert 17 to a percentage, you divide it by 100: 17/100 = 0.17.
To express this as a percentage, you multiply 0.17 by 100: 0.17 * 100 = 17%.

2. 100 + 92 = 192
Following the same logic, to find the percentage for 192:
192/100 = 1.92, so the percentage is 1.92%.

3. 15 + 13 = 28
To convert 28 to a percentage:
28/100 = 0.28
Multiply 0.28 by 100 to find the percentage: 0.28 * 100 = 28%.

4. 28 + 22 = 50
For 50, the calculations are as follows:
50/100 = 0.5
Multiply 0.5 by 100 to express it as a percentage: 0.5 * 100 = 50%.

So, the correct percentages are:
10 + 7 = 17, which is 17%.
100 + 92 = 192, which is 1.92%.
15 + 13 = 28, which is 28%.
28 + 22 = 50, which is 50%.
