Answer 3

It seems like you've entered a mathematical expression that involves fractions. The expression you provided is:

4 3/14 - 1 2/21

To simplify this expression, you can first convert the mixed numbers into improper fractions and then perform the subtraction:

4 3/14 = (4 * 14 + 3) / 14 = 59 / 14 1 2/21 = (1 * 21 + 2) / 21 = 23 / 21

Now the expression becomes:

(59 / 14) - (23 / 21)

To subtract fractions, you need a common denominator. In this case, the least common multiple of 14 and 21 is 42.

(59 / 14) * (3 / 3) = 177 / 42 (23 / 21) * (2 / 2) = 46 / 42

Now the expression becomes:

(177 / 42) - (46 / 42) = (177 - 46) / 42 = 131 / 42

So, the simplified result of the expression is 131 / 42.
