Divide. (3 3/4)÷(−2 1/2) Enter your answer as a mixed number, in simplified form, in the box.
neonofarm [45]
3 \frac{3}{4} = \frac{15}{4}

Because (4*3) + 3 = 15. Similary find the improper fraction for -2 1/2.

(15/4) / (-5/2) = -3/2

Convert -3/2 into a mixed fraction. 

Therefore, -3/2 = -1 1/2.

mihalych1998 [28]
I think is 1/27.6 because 2x equals 4 and times 3 equals 12. 5.2y equals 15.6. Then 15.6 plus 12 equals 27.6.
