Here's your original question.

What percent of 320 is 220 my answer is 6.88 make as a decimal.is this right.

-12(<)15 is less right.

-7-(-4)=-3 this subtract answer.

-9.8+(-4.9)=13.7

is these problem right.

I don't completely understand your questions.

To find what percent of 320 is 220, you need to divide: 220/320 = 0.6875 = 68.75%. This answer makes sense because 220 is more than half (50%) of 320.

I don't know about the second problem.

-7-(-4)=-3

This is correct.

-9.8+(-4.9)=13.7

The answer should be -14.7
