Question

Mr. Yu applies 1/2 ounce of fertilizer to every 5/8 square meter of his lawn. How many ounces of fertilizer does Mr. Yu use per square meter for his lawn? Enter your answer in the box as a fraction in simplest form.

Answer 1

Answer:

$\frac{4}{5}$  ounce

Step-by-step explanation:

We can use rule of three to answer this problem.

The data we have is the following:

fertilizer (ounces)        area(m^2)

            1/2                ⇒     5/8

              x                 ⇒       1

the x represents the unknown quantity of fertilizer that is used in one square meter.

Now we multiply the cross quantities and divide by the remaining value.

$x=\frac{1}{2}*1$ ÷ $\frac{5}{8}$

$x=\frac{1*8}{2*5} =\frac{8}{10} =\frac{4}{5}$

He will use 4/5 ounces of fertilizer per square meter.

Answer 2

Divide both by 5/8 because 5/8 divide by 5/8 =1
(1/2)/(5/8)
1/2*8/5
8/10
4/5
