Question

In Lixue's garden, the green pepper plants grew 5 inches in 3/4 month. At this rate, how many feet can they grow in one month? (Let 5 inches = 5/9 foot) (example 2)​

Answer 1

Answer:

$\frac{20}{27}$  feet

Step-by-step explanation:

We can simply set up a ratio to solve this problem.

Since plant grew 5/9 foot in 3/4 month, how many feet (let it be x) can it grow in 1 month??

We can set up the ratio shown below, cross multiply and solve for x:

$\frac{\frac{5}{9}}{\frac{3}{4}}=\frac{x}{1}\\\frac{5}{9}*1=\frac{3}{4}*x\\\frac{5}{9}=\frac{3}{4}x\\x=\frac{\frac{5}{9}}{\frac{3}{4}}\\x=\frac{5}{9}*\frac{4}{3}\\x=\frac{20}{27}$

Hence, we can say the pepper plant will grow 20/27 feet in 1 month.
