Calculating the Number of Children at the Hockey Match

To calculate the number of children at the hockey match, we can use the information provided. We know that the stadium can accommodate 5600 spectators for a hockey match, and one-seventh of all tickets were not sold. Additionally, it's given that three-fourths of all spectators are adults.

Let's calculate the number of children who watched the match.

Step 1: Calculate the number of tickets sold for the hockey match. - Total capacity of the stadium: 5600 spectators - One-seventh of all tickets were not sold.

The number of tickets sold can be calculated as: 5600 - (1/7 * 5600)

Step 2: Calculate the number of adult spectators. - It's given that three-fourths of all spectators are adults.

The number of adult spectators can be calculated as: (3/4) * (5600 - (1/7 * 5600))

Step 3: Calculate the number of children spectators. - The number of children spectators can be calculated as the difference between the total number of spectators and the number of adult spectators.

The number of children spectators can be calculated as: 5600 - (1/7 * 5600) - (3/4) * (5600 - (1/7 * 5600))

Let's calculate the number of children spectators based on the provided information.

Calculation

The number of children spectators at the hockey match can be calculated as: 5600 - (1/7 * 5600) - (3/4) * (5600 - (1/7 * 5600))

Result

The number of children spectators at the hockey match is 1400.
