Hello :) um Im just trying to learn this question- "Select the division equation that can be used to find the solution to the problem. 4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?"

2 ÷ 4/9= ?
4/9 ÷ 2= ?
2 ÷ 1/9= ?
2 ÷ 2/9= ?

Respuesta :

Answer: Choice A)    2 ÷ 4/9

=========================================================

Explanation:

We're told that 4/9 kg of baking soda costs $2

We can form the equation

4/9 kg = 2 dollars

We want to know the cost of 1 kg of baking soda, so we'll need to divide both sides by 4/9 to turn the "4/9 kg" into "1 kg"

Therefore,

4/9 kg = 2 dollars

turns into

1 kg = (2 ÷ 4/9) dollars

We could simplify further, but your teacher has decided not to.
