Question

Please someone help me

Answer 1

Basically it means to do Keep, Change, Flip. that's a better way to remember "reciprocal". keep the 5, change the ÷ to a × and flip the fraction 2/9 to a 9/2.

After doing that, you'll get the the first answer. 5/1 × 9/2 = 45/2

Answer 2

Answer: First option.

Explanation:

When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.

To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.

Then, the reciprocal of the fraction
`(2)/(9)` is:

`(9)/(2)`

Therefore, you can find the quotient of
`3`÷
`(2)/(9)` by multiplying
`(5)/(1)` by
`(9)/(2)`:

`5`÷
`(2)/(9)=(5)/(1)*(9)/(2)=(45)/(2)`
