Answer:
10 1/2
Step-by-step explanation:
Converting both mixed numbers to improper fractions, we get 34/5+37/10. Now we can convert them both to have a denominator of 10 and we get 68/10+37/10. Combining, we get 105/10 or 10 1/2.
The LCD here is 10.
Thus, our 6 4/5 + 3 7/10 becomes 6 8/10 + 3 7/10.
Adding the whole numbers, we get 9; adding the fractions, we get 15/10, or 1 1/2. Combine this 9 and this 1 1/2:
Thus, our 6 4/5 + 3 7/10 becomes 10 1/2.
divide the least common denominator by the original denominator
A single-digit odd number you'll get from dividing a two-digit number with 2 is 7.
If you were to divide 14 by 2, you would get 7, which is a single-digit odd number.
