To find the number of cups of nuts needed for nine cakes, you first need to determine the total amount of nuts required for one cake and then multiply it by nine.

The recipe calls for two thirds of a cup of chopped nuts for one cake. To convert this fraction into a decimal, you divide the numerator (2) by the denominator (3).

2 ÷ 3 = 0.67

So, one cake requires 0.67 cups of chopped nuts.

To find the total amount of nuts needed for nine cakes, you multiply the amount for one cake by nine.

0.67 cups/cake × 9 cakes = 6.03 cups

Therefore, you will need approximately 6.03 cups of chopped nuts for nine cakes.
