Dividing by 50 is the same as multiplying by 1/50, which is equivalent to 2/100.

The fraction 2/100 means we'll double 24000 to get 48000. Then remove 2 zeros at the end to get 480. The removal of two 0's is due to the division by 100.

Therefore, 24000/50 = 480

---------------

Dividing by 5 will follow a similar pathway. We can multiply by 1/5 aka 2/10

24000/5 = 24000*(1/5) = 24000*(2/10) = 48000/10 = 4800

Notice the numerator doubled to 48000, and then we remove a zero at the end.

All of this can be done using pure mental math only. Each answer can be confirmed with a calculator.

Write 24000 as the numerator and 50 as the denominator: 24000/50.

Notice that both the numerator and denominator have a common factor of 50.

Divide both the numerator and denominator by 50 to simplify the fraction:

(24000 / 50) / 50 = (24000 ÷ 50) / (50 ÷ 50) = 480 / 1

So, 24000/50 simplifies to 480/1, which is just 480 as a whole number. Therefore, 24000/50 = 480.
