Question

what should be subtracted from -5/3 to get -3/4

Answer 1

-5/3-(-3/4)
-5/3+3/4
-20+9/12
-11+/12

Answer 2

$- \frac{5}{3} - x = - \frac{3}{4} \\ - x = - \frac{3}{4} + \frac{5}{3} \\ - x = \frac{ - 3 \times 3 + 5 \times 4}{4 \times 3} \\ - x = \frac{ - 9 + 20}{12} \\ - x = \frac{11}{12} \\ x = \frac{ - 11}{12}$
