Question

7 1/4+13 7/8+15 3/4+17 1/8

Answer 1

Ответ:

$7 \frac{1}{4} + 13\frac{7}{8} + 15 \frac{3}{4} + 17 \frac{1}{8} = (7 \frac{1}{4} + 15 \frac{3}{4}) + (13 \frac{7}{8} + 17 \frac{1}{8} ) = 23 + 31 = 54$

Answer 2

To add the given mixed numbers, we need to convert them into improper fractions and then perform the addition. Here's the step-by-step calculation:

Step 1: Convert the mixed numbers into improper fractions: 7 1/4 = (7 * 4 + 1) / 4 = 29 / 4 13 7/8 = (13 * 8 + 7) / 8 = 111 / 8 15 3/4 = (15 * 4 + 3) / 4 = 63 / 4 17 1/8 = (17 * 8 + 1) / 8 = 137 / 8

Step 2: Add the fractions: 29 / 4 + 111 / 8 + 63 / 4 + 137 / 8

Step 3: Find a common denominator: The common denominator for 4 and 8 is 8, so we rewrite the fractions:

(29 * 2) / (4 * 2) + 111 / 8 + (63 * 2) / (4 * 2) + 137 / 8 58 / 8 + 111 / 8 + 126 / 8 + 137 / 8

Step 4: Add the numerators: (58 + 111 + 126 + 137) / 8

Step 5: Simplify the numerator: 432 / 8

Step 6: Reduce the fraction: 432 divided by 8 equals 54

Therefore, the sum of 7 1/4 + 13 7/8 + 15 3/4 + 17 1/8 is 54.
