Answer 3

To simplify the given expression involving rational numbers, follow these steps:

1. Convert all mixed numbers to improper fractions.
2. Perform the division operation first.
3. Perform the subtraction operation.
4. Simplify the resulting fraction, if necessary.

Now, let's solve the expression step by step:

Step 1: Convert mixed numbers to improper fractions. 1 = 1/1 (already in fraction form) 31/35 (no need to convert, already a fraction) 2 - 8/9 = (2 * 9 - 8) / 9 = (18 - 8) / 9 = 10 / 9 1 19/45 = (1 * 45 + 19) / 45 = (45 + 19) / 45 = 64 / 45

Step 2: Perform the division operation. 1/1 ÷ 31/35 = (1/1) * (35/31) = 35/31

Step 3: Perform the subtraction operation. 35/31 - 10/9

Step 4: Find the common denominator to subtract the fractions. The common denominator for 31 and 9 is 31 * 9 = 279.

Convert both fractions to have a denominator of 279: 35/31 * 9/9 = 315/279 10/9 * 31/31 = 310/279

Now, we can perform the subtraction: (315/279) - (310/279) = (315 - 310) / 279 = 5 / 279

So, the simplified form of the expression is 5/279.
