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
