Answer: 20 lawns could be mowed in 35 hours.

Step-by-step explanation: Lets write a ratio to represent this problem. The ratio 7:4 states that for every 7 hours you will mow 4 lawns.

Now we have to figure out how many lawns we will mow in 35 hours. Simply keep adding 7 to the left side of the ratio and 4 to the right side.

7:4

14:8

21:12

28:16

35:20

So in 35 hours, 20 lawns will be mowed.

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\frac{21}{4}

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Calculating the answer...}}\\\\---------------\\\rightarrow -\frac{3}{7} * -\frac{4}{9}\\\\\rightarrow \frac{12}{63}   \\\\\rightarrow \frac{12/3}{63/3}\\\\\rightarrow\boxed{\frac{4}{21}}\\--------------\\\rightarrow \frac{4}{21}* x= 1\\\\\rightarrow  (21)*\frac{4}{21}x= 1(21)\\\\\rightarrow 4x=21\\\\\rightarrow \frac{4x=21}{4}\\\\\rightarrow \boxed{x=\frac{21}{4}}

Hope this helps you. I apologize if it’s incorrect.

harkovskaia [24]
From the information you have given us. From my best guess, you are looking for how many kites passed inspection? if so. 28- 10= 18 - 4 = 14.       so 14 kites have passed inspection and the other 14 have not. so 50% passed the other 50% did not.
