To find the Least Common Denominator (LCD) of fractions, you first need to factor the denominators. The denominators are 40 and 18, which can be factored into 2^3 * 5 and 2 * 3^2, respectively. To find the LCD, you take the highest power of each prime factor that appears in either denominator, which in this case is 2^3 * 3^2 * 5. Therefore, the LCD of 3k/40 and k/18 is 2^3 * 3^2 * 5.

24: 2 * 2 * 2 * 3 30: 2 * 3 * 5 LCD is 2^3 * 3 * 5 = 120

LCD(3, 5, 4, 2) = 60

The LCD is 30.

15.

2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========

LCD(2, 5, 6, 3) = 30

24: 2 * 2 * 2 * 3 30: 2 * 3 * 5 LCD is 2^3 * 3 * 5 = 120
