Three friends divided some bullets equally. After all of them shot 4 bullets the total number of bullets remaining is equal to the bullets each had after division. Find the original number divided.

Lets assume remaining bullet with everyone is x so

4+x = 3*x i.e. x=2

So total number of bullet before division 3*(4+2) = 18

I divided a whole number by another whole number and the answer was 0.4705882 on my eight-digit calculator display. They were both less than 20. Can you find them?

The denominator of a rational number is greater than its numerator by 10. If the numerator is increased by 5 and denominator is decreased by 1, then the number obtained is 3/4. Find the original rational number.
