Answer:
the sum of 7 7/8 and 4 3/8 is:
7 7/8 + 4 3/8 = 49/4 or 12 1/4 (in mixed number form)
Explanation:
To add 7 7/8 and 4 3/8, we first need to make sure the fractional parts have a common denominator. In this case, the least common multiple of 8 and 8 is 8. So we can rewrite the two mixed numbers with a common denominator of 8 as follows:
7 7/8 = 7 + 7/8 = 56/8 + 7/8 = 63/8
4 3/8 = 4 + 3/8 = 32/8 + 3/8 = 35/8
Now we can add the two fractions:
63/8 + 35/8 = 98/8
We can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:
98/8 = (2 x 49)/(2 x 4) = 49/4
Therefore, the sum of 7 7/8 and 4 3/8 is:
7 7/8 + 4 3/8 = 49/4 or 12 1/4 (in mixed number form)
