Answer 3

To solve the given expression, we'll first simplify the fractions and then perform the division. Let's start:

3/4 * 5/7 * 8/9 * 7/10 : (15/16 * 14/39 * 24/25 * 13/21)

Multiplying the fractions in the numerator:

= (3 * 5 * 8 * 7) / (4 * 7 * 9 * 10) : (15/16 * 14/39 * 24/25 * 13/21)

= 840 / (4 * 7 * 9 * 10) : (15/16 * 14/39 * 24/25 * 13/21)

= 840 / (4 * 7 * 9 * 10) : (15 * 14 * 24 * 13) / (16 * 39 * 25 * 21)

= 840 / 2520 : (15 * 14 * 24 * 13) / (16 * 39 * 25 * 21)

Now, multiplying the fractions in the denominator:

= 840 / 2520 : (15 * 14 * 24 * 13) / (16 * 39 * 25 * 21)

= 840 / 2520 : (32760) / (162240)

Next, simplify the fractions:

= 1/3 : (32760) / (162240)

To divide by a fraction, we can multiply by its reciprocal:

= 1/3 * (162240) / (32760)

Now, simplify the expression:

= (1 * 162240) / (3 * 32760)

= 162240 / 98280

Finally, divide the numerator by the denominator:

= 1.64809

So, 3/4 * 5/7 * 8/9 * 7/10 : (15/16 * 14/39 * 24/25 * 13/21) is approximately equal to 1.64809.
