Alana bought some cans of paint and 1/2 of a liter of special paint additive formulated to reduce mildew. Before painting her house, she used all of the additive to put 1/8 of a liter of additive in each can. How many cans of paint did Alana buy?

Respuesta :

Answer:

Alana bought 4 cans of paint additive

Step-by-step explanation:

Proportions

If a proportional amount of x is to be distributed between y elements, each one of them gets x/y portions.

For example, if we have 100 coins and distribute evenly between 20 boxes, each box will receive 100/20=5 coins.

Alana bought 1/2 of a liter of the special paint additive and evenly distributed it between an unknown number of cans, let's call it C. We also know each can received 1/8 of a liter of the additive. That is the proportion of the 1/2 liter of additive.

We can establish the following condition:

[tex]\displaystyle \frac{1/2}{x}=\frac{1}{8}[/tex]

Solving for x:

[tex]\displaystyle \frac{1/2}{\frac{1}{8}}=x[/tex]

Transform the division into a product:

[tex]\displaystyle x=\frac{1}{2}\cdot\frac{8}{1}=4[/tex]
