The length of the wallpaper in 4 rolls is 52 meters. How many rolls do you need to buy if the repair requires 91 meters of such wallpaper?

4 rolls – 52 m.
Determine how many rolls of wallpaper are required to be enough for repairs. To do this, divide the length of the wallpaper, which is 4 rolls, by the number of rolls. We write down the solution.
52 ÷ 4 = 13 m.
That is, one roll is 13 meters.
Next, we will determine how many rolls are required for repair. We write down the resulting solution.
91 ÷ 13 = 7 rolls.
This means that in order for the wallpaper to be enough for repair, you need to buy 7 rolls.
Answer: 7 rolls are required.
