Answer 3

To solve this expression, we can perform the multiplication and division operations step by step:

First, let's multiply the fractions:

4/9 * 2/7 = (4 * 2) / (9 * 7) = 8/63

Next, let's multiply the resulting fraction by the whole number:

8/63 * 1 3/4 = 8/63 * (4 * 1 + 3/4) = 8/63 * (4 + 3/4)

To add the whole number and the fraction, we need to find a common denominator:

3/4 = (3 * 7) / (4 * 7) = 21/28

Now we can rewrite the expression:

8/63 * (4 + 21/28)

To add the whole number and the fraction, we need to find a common denominator:

4 + 21/28 = (4 * 28/28) + 21/28 = 112/28 + 21/28 = 133/28

Now we can rewrite the expression again:

8/63 * 133/28

To multiply the fractions, we multiply the numerators and the denominators:

(8 * 133) / (63 * 28) = 1064/1764

Finally, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 4:

1064/1764 = (1064/4) / (1764/4) = 266/441

Therefore, the result of the expression 4/9 * 2/7 * 1 3/4 is 266/441.
