Answer 3

To solve the expression 16/21 - 5 1/3, you need to first convert the mixed number (5 1/3) into an improper fraction and then perform the subtraction. Here's how you can do it step by step:

1. Convert the mixed number 5 1/3 into an improper fraction: 5 1/3 = (5 * 3 + 1)/3 = 16/3

2. Now, the expression becomes: 16/21 - 16/3

3. To subtract these fractions, you need a common denominator. In this case, the least common multiple of 21 and 3 is 21.

4. Rewrite both fractions with a common denominator of 21: (16/21) - (16 * 7/3 * 7) = (16/21) - (112/21)

5. Now, subtract the fractions: (16/21) - (112/21) = (16 - 112)/21 = (-96/21)

6. You can simplify this fraction further by finding the greatest common divisor (GCD) of 96 and 21, which is 3. Divide both the numerator and denominator by 3 to simplify: (-96/21) ÷ (3/3) = (-32/7)

So, 16/21 - 5 1/3 is equal to -32/7 as an improper fraction.
