Answer 2

To subtract the two mixed numbers 9 4/21 and 4 11/14, you can follow these steps:

Step 1: Convert the mixed numbers to improper fractions. 9 4/21 as an improper fraction: 9 4/21 = (9 * 21 + 4) / 21 = 193/21

4 11/14 as an improper fraction: 4 11/14 = (4 * 14 + 11) / 14 = 59/14

Step 2: Subtract the fractions. (193/21) - (59/14)

Step 3: Find a common denominator, which is the least common multiple (LCM) of 21 and 14, which is 42.

Step 4: Rewrite the fractions with a common denominator. (193/21) * (2/2) = 386/42 (59/14) * (3/3) = 177/42

Step 5: Subtract the fractions with the same denominator. (386/42) - (177/42) = (386 - 177) / 42 = 209/42

Step 6: Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which is 1 in this case. (209/42) ÷ 1 = 209/42

So, 9 4/21 - 4 11/14 = 209/42.

Now, you can simplify this fraction further. The GCD of 209 and 42 is 1, so the fraction is already in its simplest form.

Therefore, the result is 209/42.
