# How do you convert 1.7 into a fraction?

It would be $1 \frac{7}{10}$ or $\frac{17}{10}$.
Whenever there is one number after the decimal place, think of it as out of $10$. Another example would be $1.3$, the $3$ after the decimal place would be $\frac{3}{10}$, and then there is also the one which you could add to make it a mixed or improper fraction; $1 \frac{3}{10}$ or $\frac{13}{10}$.
