Answer:

Mistakes:

Used addition

Didn't flip inequality form

Corrections:

Divide each term

Instead of a positive value it should be negative

flip the direction of the inequality form

Step-by-step explanation:

- 9x \div  - 9  \leqslant 90 \div – 9

cancel the common factor

\times  \leqslant 90 \div  - 9

Divide 90 by – 9

Answer is:

\times  \leqslant  - 10

Hope this helps!

Estimate the quotient of 88.9 ÷ 15.1
kicyunya [14]

88.9 is close to 9015.1 is close to 15The idea of an estimate is to do the math without a calculator. 90 / 15 is roughly 6.

There is something I should say that is critical. If you figure out the exact answer of 5.88, you are likely going to get it wrong. This question asks you to round before you do a division. That's what estimate means.
