could someone please help me solve these two math problems? Which of the following numbers are integers? 2/13,570,0.096,-670,33.3?


write in the lowest terms 2 1/4+4 1/7?

  • Math -

    Integers are numbers without a decimal part or a fractional part.
    4, 18, -34 are integers.
    -2/5, 3.14, 25.2, 14 1/2, are not.

    When adding fractions, first add the integral part, then add the fractional part, carry-over if necessary.

    2 1/4 + 4 1/7
    = 2+4 + 1/4+1/7
    = 6 + (7+4)/28
    =6 11/28
