Question

Select the answer choice that is equivalent to 90, times, one ninth 90× 1/9

Answer 1

To find the result of 90 multiplied by one ninth, you divide 90 by 9, which equals 10.

Step-by-step explanation:

The student has asked what is the result of multiplying 90 by one ninth (90× 1/9).

We can approach this by realizing that multiplying by one ninth is the same as dividing by 9.

Just as splitting something into two equal parts gives halves, or as dividing by 3 yields thirds, dividing by 9 will give ninths.

If we divide 90 by 9, we will get sets of 10 since 9 times 10 equals 90.

Using this intuition:
90 × 1/9 = 90 / 9
90 / 9 = 10
Therefore, the answer is 10.
