lcd(6, 12, 16) = 48. 6 = 2 x 3 12 = 2^2 x 3 16 = 2^4 lcd = 2^4 x 3 = 48
The LCD is 600.
7/10 - 3/15 = 15/30 = 1/2Why?You need to find the LCD (least common denominator) which is 30. Look at the work below. You must keep in mind that whatever you do to the denominator, you must do to the numerator.7/ time 3 = 21/10 time 3 = 30- 3/ time 2 = 6/15 time 2 = -3021 - 6 = 15= 15/30 = 1/27/10 - 3/15 = ?Since 3/15 can be easily reduced to 1/5, we have:7/10 - 1/5 = ?Then, we find the LCD of 5 and 10, which is 10, by multiplying 2 to the numerator and denominator of 1/5:7/10 - 2/10 = 5/10 = 1/2.Another method includes using the basic fraction and finding the LCD:7/10 - 3/15 = ?The LCD (LCM) is 10/5 * 15/5 * 5 = 2 * 3 * 5 = 30. Thus, multiply 3 to the numerator and denominator in 7/10, and 2 to 3/15 in the same fashion.21/30 - 6/30 = 15/30 = 1/2.
In adding or subtracting dissimilar fractions, you will need first to get its LCD or least common denominator. For example: 3/2 + 5/3 = ? We will get the LCD of two and three and we will get 6 So the equation will become: 9/6 + 10/6 Then the final answer will be : 19/6
6*10^9 / 2*10^3 = (6/2) * 10^9 / 10^2 = 3*10^(9-3) = 3*10^6 or 3 million.
LCD(2, 3) = 6.
LCD(2, 3, 4, 6, 8, 10) = 120
lcd(6, 12, 16) = 48. 6 = 2 x 3 12 = 2^2 x 3 16 = 2^4 lcd = 2^4 x 3 = 48
LCD(2, 5, 6, 3) = 30

The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
The LCD is 600.

2/12=1/6 The LCD of 1/6 and 3/4=The LCD of 1/6 and 1/4=12 Therefore, 2/12 and 9/12 have the same denominator. They are equal to the original fractions. LCD=12
thirty 30 = 2 x 15 = 3 x 10 = 5 x 6 = 6 x 5 furthermore, of 2 3 5 6 the 2 and 3 are not needed, as 6 is already 2 x 3 so only 5 and 6 are in question.
the answer is 60
