A common denominator for 1 over 4 and 1 over 6 is 12 because a common multiple of 4 and 6 is 12
Multiples ( skip count )
The product of a given number and a natural number like 1,2,3 and so on
For example some multiples of 3 are 3,6,9,12
1x3=3 ,2x3=6, 3x3=9,3x4=12
List 5 multiples of 4
Don't find factors
4,8,12,16,20,24
1 over 2 and 2 over 3 find common denominator
(find multiples first than find LCF )
multiples of 2 are 2,4,6,8,10 multiples of 3 are 3,6,9,12,15
The LCF is 6 so
1 x3 3
2 x3 6 What you do to the bottom you must do to the top
2 x2 4
3 x2 6 What you do to the bottom you must do to the top
Sorry guys I could add a picture or a video
