65 worked examples are free without a code, two from every pattern. No account, either way.
Say both units aloud, then connect amount, rate and number of units.
In this one. To find an amount per one unit, divide the total amount by the number of units.
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.
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.
