Find an amount from a rate
Tickets cost $12 each. Find the cost of 18 tickets.
Show the answerHide the answer
$216
The pattern behind it: Rate as an amount per unit
Say both units aloud, then connect amount, rate and number of units.
In this one. When the rate and number of units are known, multiply them to find the total amount.
How to spot it
The word 'each' or 'per' next to a ticket, item, or hour marks this. The question asks for a total, or asks for the rate itself.
Common mistake
Children multiply when they should divide, especially when the question gives the total and the number of hours and asks for the rate per hour rather than a bigger total.
