Simplify: 3-10+9.7 Simplify: 2+3.10 divided by 5.3-9 Simplify: 16-10 divided by 5+13

  • Maths -

    3-10+9.7 = 3-10+63 = -7+63 = 56

    (2+3.10)/(5.3-9) = (2+30)/(15-9) = 32/6 = 16/3

    (16-10)/(5+13) = 6/18 = 1/3

    when you have fractions, the numerator and denominator must be evaluated separately, then finally divided.

    so, what do you get? If you have trouble, it's much better to show your work, so we can set things straight.
