Answer 3

To solve these division problems involving fractions, you can follow these steps:

1. 63/64 ÷ 45/56:

   To divide fractions, you can multiply the first fraction by the reciprocal (inverse) of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.

   So, (63/64) ÷ (45/56) is the same as (63/64) * (56/45).

   Now, multiply the numerators and denominators separately:

   (63 * 56) / (64 * 45)

   Calculate each part:

   Numerator: 63 * 56 = 3528 Denominator: 64 * 45 = 2880

   Now, simplify the fraction if possible. You can divide both the numerator and denominator by their greatest common divisor, which is 48.

   (3528 ÷ 48) / (2880 ÷ 48) = 73/60

   So, 63/64 ÷ 45/56 = 73/60.

2. 6/35 ÷ 18/25:

   Similarly, to divide fractions, multiply the first fraction by the reciprocal of the second fraction.

   (6/35) ÷ (18/25) is the same as (6/35) * (25/18).

   Now, multiply the numerators and denominators separately:

   (6 * 25) / (35 * 18)

   Calculate each part:

   Numerator: 6 * 25 = 150 Denominator: 35 * 18 = 630

   Now, simplify the fraction if possible. You can divide both the numerator and denominator by their greatest common divisor, which is 10.

   (150 ÷ 10) / (630 ÷ 10) = 15/63

   Further simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3.

   (15 ÷ 3) / (63 ÷ 3) = 5/21

   So, 6/35 ÷ 18/25 = 5/21.
