Answer 2

Calculation of (8/9) * (9/10) * (9/8)

To calculate the expression (8/9) * (9/10) * (9/8), we can multiply the numerators and denominators separately.

The numerator of the expression is calculated as follows: 8 * 9 * 9 = 648.

The denominator of the expression is calculated as follows: 9 * 10 * 8 = 720.

Therefore, the result of the expression (8/9) * (9/10) * (9/8) is 648/720.

Simplifying the Result

To simplify the fraction 648/720, we can find the greatest common divisor (GCD) of the numerator and denominator and divide both by it.

The GCD of 648 and 720 is 72.

Dividing both the numerator and denominator by 72, we get:

648/72 = 9, 720/72 = 10.

Therefore, the simplified result of the expression (8/9) * (9/10) * (9/8) is 9/10.
