Answer:
Step-by-step explanation:
First of all, the estimate will be +, because (-)(-) = (+).
So the problem boils down to approx 1 1/2 times 5, which comes out to 7 1/2.
7 1/2 is a reasonable estimate.
Please, when answer choices are given you, share them.
7.875......7.9.....or 8
-3÷2×-21÷4= 7.875
63÷8=7.875
there isn't any choices but 6/12+1/12=7/12
or 4/12+3/12=7/12
hope this helps
have a good day :)
