Answer 2

To subtract the two mixed numbers, 42 30/30 and 22 53/30, we need to find a common denominator. The common denominator in this case is 30.

First, let's convert the whole numbers into fractions with a denominator of 30:

42 = 42/1 = 1260/30 22 = 22/1 = 660/30

Now we can subtract the fractions:

1260/30 - 660/30

Since the denominators are the same, we can subtract the numerators directly:

(1260 - 660)/30 = 600/30

The resulting fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 30:

600/30 = (600 ÷ 30)/(30 ÷ 30) = 20/1 = 20

Therefore, the subtraction of 42 30/30 - 22 53/30 is equal to 20.
