Question

What is the LCD of 5/6 and -3/8 ?

Answer 1

@lizzy_oh.hi can you help me? Please?

Answer 2

What is the smallest number that you can divide evenly by 6 and 8?

Answer 3

2 right?

Answer 4

No. That is the GCF, the greatest common factor. That is the largest number that divides evenly into 6 and 8.

Answer 5

You want a number that is greater than or equal to 6 and greater than or equal to 8. When you divide that number by 6 or by 8 you get no remainder.

Answer 6

For example, the LCD of 3 and 4 is 12 because 12/3 = 4 (no remainder) and 12/4 = 3 (no remainder).

Answer 7

oh ok

Answer 8

You can list the multiples of both 6 and 8 until you find the first one they both have in common.

Answer 9

but it is negative...

Answer 10

or will that even matter?

Answer 11

Write a list of 6 multiplied by 1, 2, 3, 4, 5
Write a list of 8 multiplied by 1, 2, 3, 4, 5
What is the smallest number in both lists of multiples?

Answer 12

The number is positive.

Answer 13

ok thx and 40 is the lowest

Answer 14

40 is not a multiple of 6, so 40 can't be the LCD.

Here is a list of the first several multiples of 6 greater than 0:
6, 12, 18, 24, 30, 26, 42
Ok?
It's simply 6 * 1, 6 * 2, 6 * 3, ..., 6 * 7

Now do the same for 8.
What are the first few multiples of 8?

Answer 15

Oh HAHA I was thinking 5

Answer 16

its 24

Answer 17

Correct.
Multiples of 6: 6., 12, 18, 24, 30, 36, 42
Multiples of 8: 8, 16, 24, 32, 40
The smallest multiple 6 and 8 have in common is 24.
