Answer explanation

To convert the improper fraction to a mixed number, divide the numerator by the denominator. The whole number is 1, and the remainder is 3, so the answer is 1 3/8.

Answer explanation

To convert the improper fraction to a mixed number, divide 23 by 8. The whole number is 2, and the remainder is 7. Therefore, the mixed number is 2\frac{7}{8}.

Answer explanation

To convert the mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. In this case, 8 * 4 + 2 = 34. The fraction becomes 34/4.

Answer explanation

To convert the mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. So, 10 * 2 + 1 = 21. The fraction is then 21/2.

Answer explanation

To subtract mixed numbers, convert them to improper fractions. Then subtract the fractions and whole numbers separately. The result is 6\frac{5}{12}.

Answer explanation

To subtract mixed numbers, convert them to improper fractions. $7\frac{2}{3}-5\frac{1}{2}=\frac{23}{3}-\frac{11}{2}=\frac{46}{6}-\frac{33}{6}=\frac{13}{6}=2\frac{1}{6}$
