What is 4.8 as a fraction in its simplest form?

Answer 1

in a number such as 4321, the '4' represents the amount of "thousands", the '3' represents the "hundreds", the '2' represents the "tens" and the '1' represents the "ones". So the total number is equal to 4000 + 300 + 20 + 1.

You can see as we move right along the digits, the amount each digit is worth is divided by 10.

This tells us that in a number such as 4321.5, the '5' would represent the "tenths", just as the '8' in 4.8 represents the "tenths"

So 4.8 is really: 4 + 0.8 or "4 and 8 tenths".

To write this as a fraction you would say: 4 8/10. To unmix this fraction we can see that the whole number part ('4') is equivalent to 40/10 and so together it is 48/10. We can simplify this even further by dividing the numerator and denominator each by 2 giving 24/5.
4.8 = 48/10 or 24/5
