Answer: Your answer is 4 1/20
Step-by-step explanation: Change the mixed numbers into improper fractions: 1 7/8 = 15/8, 3 3/8 = 27/8, 1 1/5 = 6/5. After you've done that plug them in. So the equation is now (27/8 - 6/5) + 15/8. Then, remove the parentheses (27/8 - 6/5). Next, look for the less common multiplier which is 40. Fix the fractions based on the LCM 40. 135/40 - 48/40 + 75/40. So, since we have the same denominators we combine the fractions into one. 135 - 48 + 75 / 40. We add subtract then add the numbers and get 162. 162/40, lastly cancel the common factor which is 2 and make the improper fraction into a mixed number which is 4 1/20.
