I post some question this morning why have no one help me

  • Math 116 -

    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
