To arrange the numbers 50, 45, 15, and 150 to form a true proportion, you can set them up as follows: 50/150 = 15/45. This simplifies to 1/3 = 1/3, which is a true proportion. Thus, the arrangement of the numbers is (50, 150) and (15, 45).
The answer to the LCM of 45 and 15 is 45.
3 * 15 = 45 or 15 = 45 / 3 or 3 = 45 / 15
45 - 15 - 15 = 15
15% of 45 pounds= 15% * 45= 0.15 * 45= 6.75 pounds

To find out how many cookies are needed for 30 students, you can set up a proportion based on the number of cookies serving the number of students. In this case, 45 cookies serve 15 students, so the ratio of cookies to students is 45:15. To find out how many cookies are needed for 30 students, you can set up the proportion: 45/15 = x/30. Cross multiplying, you get x = (45 * 30) / 15 = 90 cookies. Therefore, 90 cookies are needed to serve 30 students.
The answer to the LCM of 45 and 15 is 45.
3 * 15 = 45 or 15 = 45 / 3 or 3 = 45 / 15
45 - 15 = 3030 - 15 = 15
45 - 15 - 15 = 15
15% of 45 pounds= 15% * 45= 0.15 * 45= 6.75 pounds
45
Since 45 is a multiple of 15, it is automatically the LCM.
15% of $45.00= 15% * 45= 0.15 * 45= $6.75
