Respuesta :
1050 feet of room can be painted with 3 gallon of paint
Solution:
Given, 280 ft of room painted with 4/5 gallon of paint
We have to find how many feet can you paint with 3 gallon
Now, according to given information,
[tex]\frac{4}{5}[/tex] gallon of paint ⇒ 280 feet of room
Then, 3 gallon of paint ⇒ "n" feet of room
So by chris cross method, we get
[tex]\begin{array}{l}{n \times \frac{4}{5}=3 \times 280} \\\\ {n=3 \times 280 \times \frac{5}{4}} \\\\ {n=3 \times 70 \times 5} \\\\ {n=210 \times 5=1050}\end{array}[/tex]
Hence, we can paint 1050 ft of the room with 3 gallons of paint.
