In bucket

In a bucket of 87 oranges, 1/3 are spoiled, and a family member eats the remaining. How many oranges are consumed by the member of the family?

Correct answer:

f =  58

Step-by-step explanation:

$$\begin{gathered} b=87 \\ s=\frac{1}{3}\cdot b=\frac{1}{3}\cdot 87=\frac{1\cdot 87}{3}=\frac{87}{3}=29 \\ f=b-s=87-29=58 \end{gathered}$$
