What is four fifths minus three tenths?

Answer 1

4 3

5 10

Firstly you need to make the denominator (the bottom number) equal. You should be able to see, that 5 can be multiplied by 2 to get 10.

However, you MUST remember, whatever you do to the bottom, you must do to the top.

So when you multiply the denominator 5 by 2 to equal 10, you must also multiply the nominator 4, by 2 as well to get 8.

This gives the fractions:

8 3

10 10

When the denominator is the same, you can simply subtract the nominators, so you would do 8 - 3 which equals 5.

Here the denominator (10) does not change so this would leave you with,

5

10

You should then simplify this into the simplest form. You know that 5 goes into 10 (by multiplying by 2) so by dividing both the nominator (5) and denominator (10) by 5, you get the final answer:

1

2

I hope this helped, I did not know how much detail you wanted through the stages, so I hope that this was enough. :)
