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 the greatest common factor of 18 and 40?
The greatest common factor is the highest number that divides exactly into two or more numbers. 18: 1, 2, 3, 6, 9, 18 40: 1, 2, 4, 5, 8, 10, 20, 40 The GCF for 18 and 40 is 2.
What fraction is greater three fifths or five eights?
LCD(5, 8) = 40.So 3/5 = 24/40 and 5/8 = 25/40. The second fraction, that is 5/8, is greater.
