First estimate the answer. Then multiply to find the exact answer simplify all answers 4 1/4 • 9 2/3
What is 4 * 10?
40
Right. That's a good estimate.
Now multiply those fractions to find the exact answer.

To estimate the answer, you can round the numbers to the nearest whole numbers and then perform the multiplication.
4 1/4 can be rounded to 4 and 9 2/3 can be rounded to 10.
So the estimated calculation would be: 4 * 10 = 40
To find the exact answer, you need to convert the mixed numbers into improper fractions and then perform the multiplication.
4 1/4 can be converted to an improper fraction as (4 * 4 + 1) / 4 = 17/4
9 2/3 can be converted to an improper fraction as (9 * 3 + 2) / 3 = 29/3
Now, multiply the two improper fractions: (17/4) * (29/3)
To multiply fractions, you multiply the numerators together and the denominators together.
So, (17 * 29) / (4 * 3)
The numerator is 493 and the denominator is 12.
Thus, the exact answer after simplifying is 493/12.
