You're right. A is the right answer.
To simplify the expression, we need to perform the addition and subtraction operations. Let's break down the steps:
Step 1: Convert the mixed numbers to improper fractions.
2 3/18 can be converted to the improper fraction 39/18.
5 3/12 can be converted to the improper fraction 63/12.
4 2/4 can be converted to the improper fraction 10/4.
Step 2: Perform the addition and subtraction.
Adding the fractions:
39/18 + 63/12 = (39*2)/(18*2) + 63/12 = 78/36 + 63/12 = (78 + 63)/36 = 141/36
Subtracting the fraction:
141/36 - 10/4 = (141*4)/(36*4) - 10/4 = 564/144 - 10/4 = (564 - 360)/144 = 204/144
Step 3: Simplify the resulting fraction.
Both the numerator and denominator of 204/144 can be divided by 12:
204/12 ÷ 144/12 = 17/12
Step 4: Convert the improper fraction back to a mixed number.
17/12 can be written as the mixed number 1 5/12.
So, the simplified expression is 1 5/12. Therefore, option d) 3 1/1 is not correct. Option b) 7 1/12 is the correct answer.
