Question

Write the decimal as a fraction or a mixed number in simplest form. 3.4

Answer 1

As a mixed number, it is 3 2/5 and as an improper fraction it is 17/5

Answer 2

Remember the decimal places...

The 4 is in the tenths place. So you could say 4 tenths or 4/10. Don't forget the 3!
\[\large 3\frac{ 4 }{ 10 }\]We can simplify the 4/10 to 2/5, by dividing the numerator and denominator by 2. So we have:
\[\large 3\frac{ 2 }{ 5 }\]
