Answer 1

Answer:

Negative 140 divided by negative 7 = 20

Step-by-step explanation:

Gena and her friends each estimated the quotient of –137.56 divided by –6.12 using compatible numbers.

Using Compatible Numbers: we round up each negative number given to the nearest whole number.

Hence:

-137.56 = -140

-6.12 = -7

Hence:

-140/-7 = -20

Therefore, the best estimate using compatible numbers is Negative 140 divided by negative 7 = 20
