Answer 2

To add the fractions 1 10/57 and 4 56/63, you first need to convert the mixed numbers into improper fractions.

For 1 10/57: Multiply the whole number (1) by the denominator (57) and add the numerator (10) to get the new numerator. The denominator remains the same. 1 * 57 + 10 = 57 + 10 = 67 So, 1 10/57 is equivalent to the improper fraction 67/57.

For 4 56/63: Multiply the whole number (4) by the denominator (63) and add the numerator (56) to get the new numerator. The denominator remains the same. 4 * 63 + 56 = 252 + 56 = 308 So, 4 56/63 is equivalent to the improper fraction 308/63.

Now, you can add the fractions: 67/57 + 308/63

To add fractions with different denominators, you need to find a common denominator. In this case, the least common multiple (LCM) of 57 and 63 is 3591.

First, find the equivalent fractions with the common denominator: 67/57 * (63/63) = 4263/3591 308/63 * (57/57) = 17376/3591

Now, you can add the fractions with the common denominator: 4263/3591 + 17376/3591 = (4263 + 17376)/3591 = 21639/3591

The result is 21639/3591.
