Answer 2

To simplify the fraction (31 * 15) / (53 * 40), you can first perform the multiplication in the numerator and the denominator, and then simplify the resulting fraction:

Numerator: 31 * 15 = 465 Denominator: 53 * 40 = 2120

Now the fraction becomes 465 / 2120. To simplify it further, find the greatest common divisor (GCD) of the numerator and denominator, and then divide both of them by the GCD:

The GCD of 465 and 2120 is 5.

Divide both the numerator and denominator by 5: Numerator: 465 / 5 = 93 Denominator: 2120 / 5 = 424

So, the simplified fraction is 93/424.
