Math question: What is the least prime factor of the number 1340?

To find the least prime factor of 1340, we can divide it by successive prime numbers. Dividing by 2 gives us 670, dividing by 5 gives us 134, and dividing by 67 gives us 2. Therefore, the least prime factor of 1340 is 2.

Math question: If 20% of a number is 268, then what is 80% of the number?

To find 80% of a number when 20% is given, we can use proportions. Let the number be x. By setting up the proportion (20/100) = 268/x, we can solve for x. Cross-multiplying, we find x = (268 * 100) / 20 = 1340. Hence, 80% of 1340 is (80/100) * 1340 = 1072. Therefore, 80% of the number 1340 is equal to 1072.

Math question: If you divide a number by 10 and then add 420, the result is 1340. What is the original number?

To find the original number, we can reverse the steps. Subtracting 420 from 1340 gives us 920. Finally, multiplying 920 by 10 gives us the answer: 9200. Therefore, the original number is 9200.
