can someone answer my queston
-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)
thats exactley what i got but it wasnt right i dont know why
did they give you what they think the correct answer is?
isn't -2 3/4 = -11/4
no its just multiple choice
what are your choices?
-11/4-9/10 would then be -55/20-18/20=-73/20=-3 13/20
ok, but it is negative 2 and three fourths right, not negative 2 times three fourths
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
ya so its -11/4
Thank you Mr.t
ok can you show me how you got that...?
-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?
sorry its still a negative so its -11/4
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
YES YES IT IS THANKYOU!!!!!!!!!!!!!!!!!!!!
oh well nevermind then sorry about that
pcorn i gave you a medal for correcting me thanks
