To divide 53/5 by 42/3 :
Changing the mixed numbers to improper fractions gives the division
28/5 divided by 14/3
To divide by a fraction, you can invert its values (multiply by the reciprocal), giving
28/5 x 3/14
Multiply the numerators 28 x 3 = 84 and the denominators 5 x 14 = 70
The answer is 84/70 which reduces to 1 14/70 or 1 1/5
