To divide 10 2/5 by 2 1/4, we need to convert these mixed numbers into improper fractions.
10 2/5 can be written as an improper fraction as:
10 = 10/1
Adding the fraction part:
10 + 2/5 = 50/5 + 2/5 = 52/5
Similarly, 2 1/4 can be written as an improper fraction as:
2 = 2/1
Adding the fraction part:
2 + 1/4 = 8/4 + 1/4 = 9/4
Now, we can divide 52/5 by 9/4:
52/5 ÷ 9/4 = (52/5) * (4/9) = 208/45
Now, we need to convert this improper fraction back into a mixed number.
The whole number part of the mixed number is the result of dividing 208 by 45, which is 4.
The remainder is 208 - (45 * 4) = 28
So the mixed number is 4 28/45, which is equal to the quotient of 10 2/5 divided by 2 1/4.

Apologies for the mistake. You are correct.
To divide 10 2/5 by 2 1/4, we can multiply by the reciprocal of the divisor.
The reciprocal of 2 1/4 is 4/9 (flipped upside down).
So, we have (10 2/5) / (2 1/4) = (52/5) / (9/4)
To simplify, we multiply the numerator by the reciprocal of the denominator:
(52/5) * (4/9) = (208/5) / (9/4)
To further simplify, we multiply by 20/20:
[(208 * 20) / (5 * 20)] / [(9 * 20) / (4 * 20)] = (4160/100) / (180/80)
Now, simplifying further:
(4160/100) * (80/180) = 4160/225
Now, we need to convert this improper fraction back into a mixed number:
4160 ÷ 225 = 18 remainder 70
Therefore, the final answer is 18 and 70/225, which can be simplified to 4 and 28/45.

I apologize for the confusion. Here's a simpler explanation:
To divide 10 2/5 by 2 1/4, we can convert both mixed numbers into improper fractions:
10 2/5 = (10 * 5 + 2) / 5 = 52/5
2 1/4 = (2 * 4 + 1) / 4 = 9/4
Now, we divide 52/5 by 9/4:
(52/5) / (9/4) = (52/5) * (4/9) = 208/45
To convert this improper fraction back into a mixed number, we divide the numerator by the denominator:
208 ÷ 45 = 4 with a remainder of 28.
Thus, the quotient is 4 28/45.
