Question

a restaurant has 30 tables in its dining room. it takes a waiter 10 minutes to set 8 tables. at this rate, how long will it take the waiter to set all the tables in the dining room? now find how long it will take to set all 30 tables. minutes tables 10 8 10/8 1 30

Explanation:

Step1: Find time per table

To find the time taken to set 1 table, we divide the total time by the number of tables. So, time per table is $\frac{10}{8}$ minutes.

Step2: Calculate time for 30 tables

To find the time for 30 tables, we multiply the time per table by 30. So, time = $\frac{10}{8} \times 30$
First, simplify $\frac{10}{8}=\frac{5}{4}$. Then, $\frac{5}{4} \times 30=\frac{150}{4} = 37.5$ minutes.

Answer:

It will take the waiter 37.5 minutes to set all 30 tables. For the table, the first box (above the 30) is $\frac{10}{8}$ (time per table) and the second box (below, total time) is 37.5. But the main answer for the time is 37.5 minutes.
