Answer: -6
Explanation:
(-21/5) / (-7/-10)
Since there is two negatives in -7/-10 the negative will cancel out, but only in -7/-10
(-21/5)/(7/10)
You can now divide what’s in the parentheses (which will give you (-21/5)/(10/7)
(-21/5) / (10/7) = -3 X 2 (just divide 10 by 5 and -21 by 7, when dividing fractions you divided the opposing numerator by the denominatior)
-3 x 2 = -6
Hope that makes sense :)
