is these problem right.
my problem have not been answer what the problem
220/320 = .6875 = 68.75%
(I don't know how you got 6.88)
-12 < 15 ---true

-9.8 + (-4.9) = -14.7
2 negatives when added are still negative, think of going into debt twice, you are still in debt.
Let's go through each of your questions one by one:
1. What percent of 320 is 220? To find the percentage, you need to divide the smaller number (220) by the larger number (320) and then multiply the result by 100. In this case, the calculation would be (220/320) * 100 = 68.75%. So your answer of 6.88 is incorrect. The correct percentage is 68.75%.
2. -12(<)15. The symbol "<" represents the "less than" operator. In this case, you are comparing -12 with 15. The statement -12(<)15 means that -12 is less than 15, which is correct.
3. -7-(-4)=-3. In this equation, you have two negative numbers and a subtraction operation. When subtracting a negative number, it is equivalent to adding the positive value of that number. So, -7-(-4) can be rewritten as -7+4, which equals -3. Therefore, your answer of -3 is correct.
4. -9.8+(-4.9)=13.7. In this equation, you have two negative numbers and an addition operation. When adding two negative numbers, you simply add their magnitudes and keep the negative sign. So, -9.8+(-4.9) equals -14.7, not 13.7. Therefore, your answer of 13.7 is incorrect.
In summary:
- The percentage of 320 that 220 represents is 68.75%.
- -12 is indeed less than 15.
- -7-(-4) equals -3.
- -9.8+(-4.9) equals -14.7, not 13.7.
