2 1⁄2 ÷ 1 3⁄6 please help me with the RIGHT answer.

Answer:

$1\frac{2}{3}$

Step-by-step explanation:

We want to simplify:

$2 \frac{1}{2} \div 1 \frac{3}{6}$

This is the same as:

$2 \frac{1}{2} \div 1 \frac{1}{2}$

Now let us convert the mixed numbers to improper fractions.

$\frac{5}{2} \div \frac{3}{2}$

We multiply by the reciprocal of the second fraction to get:

$\frac{5}{2} \times \frac{2}{3}$

Cancel out the common factors to obtain:

$\frac{5}{3} = 1 \frac{2}{3}$
