What is 3/10 divided by 1/3

A: 10

B: 10/9

C: 3/30

D: 9/10

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.

In this case, we have $\frac{3}{10} \div \frac{1}{3}$. The reciprocal of $\frac{1}{3}$ is $\frac{3}{1}$.

So, we have $\frac{3}{10} \times \frac{3}{1}$.

Multiplying the numerators gives us $3 \times 3 = 9$, and multiplying the denominators gives us $10 \times 1 = 10$.

Therefore, $\frac{3}{10} \div \frac{1}{3} = \frac{9}{10}$.

So, the answer is $\boxed{\text{(D) } \frac{9}{10}}$.

I apologize for any confusion caused. I made an error in my previous response. Let's correct it:

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.

So, we have $\frac{3}{10} \times \frac{3}{1}$.

Therefore, $\frac{3}{10} \div \frac{1}{3} = \frac{9}{10}$.

So, the correct answer is $\boxed{\text{(D) } \frac{9}{10}}$.

To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator.

So, to divide 3/10 by 1/3, you multiply 3/10 by the reciprocal of 1/3, which is 3/1.

Multiplying 3/10 by 3/1, you get:

(3/10) * (3/1) = (3 * 3)/(10 * 1) = 9/10

Therefore, the answer is option D: 9/10.
