Question

Select all statements that show correct reasoning for finding 15 ÷ 2/9 * Multiply 15 by 2, then divide by 9. Multiply 15 by 9, then divide by 2. Multiply 15 by 1/9, then multiply by 2. Multiply 15 by 9, then multiply by 1/2

Answer 1

Answer:

Multiply 15 by 9, then divide by 2.

Step-by-step explanation:

We need to solve the given expression.

$15\div \dfrac{2}{9}$

We know that, $a\div \dfrac{b}{c}=a\times \dfrac{c}{b}$

We have,

a = 15, b = 2 and c = 9

So,

$15\div \dfrac{2}{9}=15\times \dfrac{9}{2}\\\\=\dfrac{15\times 9}{2}\\\\=\dfrac{135}{2}\\\\=67.5$

So, the steps are "Multiply 15 by 9, then divide by 2".
