LCD(3, 40) = 120
It is: 40
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.
If that's 3/8 and 7/10, the LCD is 40.If not, it's 13490
40. All three numbers will equal each other when they multiply to 40.
LCD(32, 40) = 160
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)
LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320
Consider the fractions ( \frac{3}{4} ) and ( \frac{1}{5} ). The least common denominator (LCD) of these fractions is 20, since 20 is the smallest multiple of both 4 and 5. However, the product of the denominators ( 4 \times 5 ) equals 20, which does not meet the condition. Instead, if we use ( \frac{3}{8} ) and ( \frac{1}{5} ), the LCD remains 40 (the smallest multiple of 8 and 5), while the product of the denominators ( 8 \times 5 = 40 ) also remains consistent. This demonstrates that while the LCD can be determined, the product of the denominators yields a different result.
