Math question: How many whole number multiples of 13 are between 50 and 200?

To find the number of whole number multiples of 13 between 50 and 200, we can set up an inequality and solve it. The smallest multiple of 13 greater than or equal to 50 is 52 (which is 13*4) and the largest multiple less than or equal to 200 is 195 (which is 13*15). Thus, we need to count the number of terms in the arithmetic sequence formed by multiples of 13, starting from 52 and ending at 195. The common difference is 13, so the total number of terms, n, can be calculated using the formula: n = (last term - first term)/common difference + 1, which will be (195 - 52)/13 + 1 = 15 terms. Therefore, between 50 and 200, there are 15 whole number multiples of 13.

Question: What is the largest prime number less than 50, and what is the remainder when dividing it by 6?

The largest prime number less than 13 is 11. When dividing 11 by 6, the remainder is 5.

Math question: What is the product of the integer obtained by multiplying 13 by 4 and the result after dividing that product by the sum of 13 and 5?

To find the product of 13 multiplied by 4, we get 52. Next, we find the sum of 13 and 5, which is 18. Therefore, dividing 52 by 18 gives us approximately 2.8889.
