    -2 3/4 - 9/10 make -2 3/4 into a improper fraction -5/4-9/10 find common denominator -25/20-18/20 subtract numerators -43/20 or -2 (3/20)

    -11/4-9/10 would then be -55/20-18/20=-73/20=-3 13/20

    but you have to make it into an improper fraction and to do that you have to multiply the denominator by the single number and add the numerator

    -2 3/4 so negative 2x4=8+3 equals 11 with a denominator of 4

    a negative plus a positive is really subtraction.... -2(4)=-8+3=-5 how do you get rid of your negative?

    Ok..... I guess that works -11/4 - 9/10 -55/20-18/20=-73/20 simplify -3 (13/20) still isn't one of your answers
