Question

A plant food recipe calls for 1 1/2 cups of fertilizer for every 3 3/4 cups of water. If a gardener makes a 42 cup of plant food using the proportions of the recipe which statement is true

Answer 1

Explanation:

Firstly we need to ratio the fertilizer to plant food:

`1(1)/(2) : 3 (3)/(4)`

Lets add these two values together:

`1(1)/(2) + 3 (3)/(4) = 5 (1)/(4)`

So now we know one of each, we can divide the above value into 42 to find out the amount:

42 ÷
`5(1)/(4)` = 8

So this means that 8 portions of each can be used. This can calculate the full ratio by multiplying each ratio by 8:

`(1(1)/(2) * 8) : (3 (3)/(4) * 8)` =

12 : 30

You have not included the statements although I hope you can decide which statement is true via the explanation above, feel free to comment the different statements if need be.

Hope this helps!
