Answer 2

To multiply these fractions together, you can follow these steps:

Step 1: Multiply the whole number by the numerator of the first fraction. 4 * 2/5 = 8/5

Step 2: Multiply the fractions together, numerator by numerator and denominator by denominator. (8/5) * (15/17) * (7/20) = (8 * 15 * 7) / (5 * 17 * 20)

Step 3: Simplify the fraction if possible. (8 * 15 * 7) / (5 * 17 * 20) = 840 / (5 * 17 * 20)

Step 4: Further simplify if possible. In this case, you can see that 5 and 20 have a common factor of 5, so you can cancel them out. 840 / (5 * 17 * 20) = (840 / 5) * (1 / 17) * (1 / 4) = 168 * (1 / 17) * (1 / 4)

Now, the fraction is in its simplest form.

So, 4 2/5 * 15/17 * 7/20 = 168/17 * 1/4 = 168/68

To simplify the final fraction, you can find the greatest common divisor (GCD) of 168 and 68, which is 4, and then divide both the numerator and denominator by 4:

(168/68) ÷ 4 = (42/17) ÷ 4 = 42/17

So, the result of the expression is 42/17.
