A concert promoter wants to give away 240 tickets to 3 radio stations. Which basic math fact can he use to find 240 image 3 using mental math?
3 times what = 24?
To find 240 divided by 3 using mental math, the concert promoter can use the basic math fact of division or sharing equally.
Here's the step-by-step process to find the answer mentally:
1. Divide the first digit of 240, which is 2, by 3. Since 2 is less than 3, the answer will be less than 1. However, this digit alone won't give us an accurate result.
2. To continue, bring down the next digit, which is 4. Now we have 24.
3. Divide 24 by 3 mentally. 3 can go into 24 evenly without a remainder. Therefore, the answer is 8.
4. So, 240 divided by 3 is equal to 80.
Using this basic math fact, the concert promoter can determine that each radio station should receive 80 tickets.
