1 1/3 divided by 3 + 1/3

Phantasy [73]

The first step to solve this problem is to convert the first mixed number to an improper fraction.
$\frac{4}{3}$ ÷ 3 + $\frac{1}{3}$
Dividing is equivalent to multiplying with the reciprocal value,, so next you will need to change the signs.
$\frac{4}{3}$ x $\frac{1}{3}$ + $\frac{1}{3}$
Multiply the fractions
$\frac{4}{9}$ + $\frac{1}{3}$
Finally,, add the two fractions together to get your final answer
$\frac{7}{9}$
This means that the correct answer to your question is $\frac{7}{9}$ .
Let me know if you have any further questions
