Question

the daily supply of oxygen for a particular multicellular organism is provided by 625 sq ft of lawn. A total of 4,375 sq fy of lawn would provide the daily supplies of oxygen for how many organisms?

Answer 1

Hello!

Note that 625ft² of lawn is sufficient for 1 organism.

For how many organisms 4,375ft² will be sufficient?

We can solve it using the rule of three, look:

`\begin{gathered} \frac{1\text{ organism}\rightarrow625}{x\text{ organisms}\rightarrow4,375} \\ \\ 625x=4,375 \\ x=(4,375)/(625) \\ \\ \boxed{x=7\text{ organ}\imaginaryI\text{sms}} \end{gathered}`

Answer:

It will be sufficient for 7 organisms.
