Question

1/6 + 3/8

A. 4/6
B. 4/8
C. 4/14
D. 13/24

Answer 1

Your very first step would be to identify the Lowest Common Denominator (LCD). What is it?

Answer 2

As what mathmale said, you locate the LCD to reconfigure the 6 and 8 to the same values.

Answer 3

On some point in the lines, 6 and 8 can be multiplied and share a common factor. Which one is the LEAST?

Answer 4

\[\frac{ 1 }{ 6 } = \frac{ numerator }{ denominator }\]

\[\frac{ 3 }{ 8 } = \frac{ numerator }{ denominator }\]

Answer 5

6 x 8 = 48

Answer 6

That is true, but we want the lowest common denominator. There is a number "lower" than 48 that 6 and 8, can both go into.

Answer 7

The best way to do this, is to take the smallest number and multiply it by increasing numbers from 1 -> and so on

6 x 1 = 6

Can 8 go into 6?
no

6 x 2 = 12
Can 8 go into 12?
no

6 x 3 = 18
Can 8 go into 18?
No

6 x 4 = 24
Can 8 go into 24?

You tell me :)

Answer 8

yes

Answer 9

How many times

Answer 10

???

Answer 11

8 times

Answer 12

13 @ShadowLegendX

Answer 13

so i think its D

Answer 14

8 goes into 64, 8 times

8 goes into 24...3 times

Answer 15

so the answer

Answer 16

Now with this information

6 goes into 24, 4 times

8 goes into 24, 3 times

We have our LCD

\[\frac{ 1 }{ 6 }(\frac{ 4 }{ 4 }) + \frac{ 3 }{ 8 }(\frac{ 3 }{ 3 })\]

Answer 17

b

Answer 18

We get,

\[\frac{ 4 }{ 24 } + \frac{ 9 }{ 24 } = \frac{ 13 }{ 24 }\]

Answer 19

thanks !!!!

Answer 20

No problem :)
