What's 4 divided 2/3 in a model?

Stels [109]

Here is you're answer:

In order to get you're answer you first need to solve this equation then draw the model.

$4 \div \frac{2}{3}$
$\frac{4}{1} \div \frac{2}{3}$
Use KCF
$\frac{4}{1} \times \frac{3}{2}$
Now solve:
$\frac{4}{1} \times \frac{3}{2} = \frac{12}{2}$
Simplify:
$\frac{12}{2} \div 2 = \frac{6}{1} = 6$
$= 6$

"Now draw four boxes, then draw another box under each box with 3 parts in each box. Then color 2 parts of each box, Add each box to equal 6 which is you're answer."

Therefore you're answer is "6."

Hope this helps!
