If thirty-one (31) cups of fruit punch will be needed, and a one (1) litre bottle of fruit punch contains 7 cups, how many litres does Oliver need to buy for thirty-cups (31)? Show working
To find the number of liters Oliver needs to buy, we need to divide the total number of cups needed by the number of cups in one liter.
31 cups ÷ 7 cups/liter = 4.43 liters
Therefore, Oliver needs to buy approximately 4.43 liters of fruit punch for 31 cups.
To determine how many liters Oliver needs to buy for 31 cups of fruit punch, we need to find the number of liters in 31 cups.
Given that a 1-liter bottle of fruit punch contains 7 cups, we can set up a ratio:
1 liter / 7 cups = x liters / 31 cups
To solve for x (the number of liters needed for 31 cups), cross multiply:
1 liter * 31 cups = 7 cups * x liters
31 liters = 7x
To find the value of x, we divide both sides of the equation by 7:
31 liters / 7 = 7x / 7
4.43 liters = x
Therefore, Oliver needs to buy approximately 4.43 liters of fruit punch for 31 cups.
