ok, but it is negative 2 and three fourths right, not negative 2 times three fourths
anonymous
  • anonymous
yes its negative 2 and three fourths

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

-11/4-9/10

ok can you show me how you got that...?

-2 3/4 so negative 2x4=8+3 equals 11 with a denominator of 4
anonymous
  • anonymous
a negative plus a positive is really subtraction.... -2(4)=-8+3=-5 how do you get rid of your negative?
anonymous
  • anonymous
sorry its still a negative so its -11/4
anonymous
  • anonymous
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
