Question

how do u write 5.6 as a fraction in simplest form

Answer 1

The first answer to your question is 5 6/10 because you pronounce the decimal as six tenths. There is a simpler form of 5 6/10, it is 5 3/5. This is because you divide six by 2 and get 3 and divide 10 by two and get 5. 

Answer 2

The answer to your question is 5 6/10

Your 5 is a whole number and your 6 is past the decimal point and is in the tenth column therefore that's why you get your 6/10.
