Some sort of number I'm guessing
2
2 goes into 4. 3 goes into 6 or 9. 5 goes into 10, 15, 20, 25, 30. 7 goes into 14, 21, 28.
14/30= 14/2=7 30/2=15. Therefore 14/30 simplified= 7/15.
find the missing number 8-4-9 14-5-2 18-1-blank?
0.0714
10
Blank = zero.
62, the sequence is following a pattern of 2's in the 2nd, 4th, 6th etc place, and the odd places are following a rule of 2*(n-2)+2 i.e. double the number two places in front and +2. Starting with 2 this would go 2, 6, 14, 30, 62, 126, 254, 510, 1022 etc.
14 goes into 30 two and 1/7 times, or two whole times with 2 left over dangling.
2
The numbers 1,2,3,5,6,10,15,and 30 go into 30 evenly.
2 goes into 4. 3 goes into 6 or 9. 5 goes into 10, 15, 20, 25, 30. 7 goes into 14, 21, 28.
14/30= 14/2=7 30/2=15. Therefore 14/30 simplified= 7/15.
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
28 goes into 7 and 2, while 30 goes into 15 and 2.
find the missing number 8-4-9 14-5-2 18-1-blank?
The LCM is 210.
