Answer:
7 / 8
Explanation:
In order to add fractions, the denominators must be the same.
1 / 2 + 3 / 8
Find the least common denominator by prime factorization.
2:2
8:2, 2, 2
To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.
LCD = 2 × 2 × 2 = 8
Multiply 1 / 2 times 4 / 4 so that it will have a denominator of 8.
1 / 2 × 4 / 4 + 3 / 8
= 4 / 8 + 3 / 8
= 7 / 8
Hope this helps :)
