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.

What is 7 over 8 plus 4 over 5 and 9 over 20 explain?
First you have to find the LCD. LCD=40 Then you multiply each fraction top and bottom to get 40 as the LCD. 35/40+32/40+18/40 Then you need to add. 85/40 Lastly you simplify. So the answer is 19/8(19 over 8)
