Answer:
4
Explanation:
take 1 9/10 change it to 19/10 + 3/4. You will need to have a common denominator for any addition or subtraction with fractions. We multiply 19/10 by 4 to get 76/40. Multiply 3/4 by 10 to get 30/40. Now we have a common denominator.
Add across 76 + 30 = 106/40. Now simplify. How many times does 40 go into 106?
4 times. No remainder.
