A recipe for chocolate cookies requires 2/3 of a stick of butter. Lena adds 1/8 of a stick of butter at a time to the mixing bowl until the amount she needs to add is less than 1/8 of a stick, at which point she adds the remaining amount of butter required. How many total times does Lena add butter to the mixing bowl?

6 times

Step-by-step explanation:

Let the number of time Lena adds butter to the mixing bowl be represented as x

A recipe for chocolate cookies requires 2/3 of a stick of butter. Lena adds 1/8 of a stick of butter at a time to the mixing bowl until the amount she needs to add is less than 1/8 of a stick, at which point she adds the remaining amount of butter required.

Hence,we have the equation

1/8x = 2/3

x = 2/3 ÷ 1/8

x = 2/3 × 8/1

x = 16/3

x = 5.3333333333 times

The total number of times that Lena adds butter to the mixing bowl is 6 times.

This is because, after adding 1/8 of the butter 5 times, the amount left is less than 1/8 of a stick, which she still adds to the mixing bowl.

Hence in total, she added butter to the bowl 6 times
