Help what does 2 1⁄3 ÷ 1 1⁄2 =

azamat

Answer:

$1\frac{5}{9}$

Step-by-step explanation:

This is the answer because:

1) Reduce the expression, if possible, by cancelling the common factors.

2) You can also find the reciprocal of 1 1/2 = 3/2 while dividing the expression:

1. Convert both fractions into improper fractions:

$2\frac{1}{3} = \frac{7}{3}$

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

2. Divide both fractions:

$\frac{7}{3}$ ÷ $\frac{3}{2}$ = $\frac{7}{3}$ x $\frac{2}{3}$ = $\frac{14}{9}$ = $1\frac{5}{9}$

Therefore, the answer is $1\frac{5}{9}$

Hope this helps! :D
