70 x 2 = 140 28 x 5 = 140 and so on.
2 x 2 x 5 x 7 = 140
2 x 2 x 5 x 7 = 140
140 = 1 x 140.......... 2 x 70.......... 4 x 35.......... 5 x 28.......... 7 x 20.......... 10 x 14
5 x 28 = 140!
75 = 3 x 5 x 5 140 = 2 x 2 x 5 x 7. GCF is thus 5.
140 = 2 x 2 x 5 x 7
70 x 2 = 140 28 x 5 = 140 and so on.
2 x 2 x 5 x 7 = 140
2 x 2 x 5 x 7 = 140
2 x 2 x 5 x 7 = 140
140 = 2 x 2 x 5 x 7
4 and 5 and 7 have no common factors. So their LCM is 4 x 5 x 7 = 140.
2 x 2 x 5 x 7 = 140 5 x 9 x 9 = 405 HCF is 5 LCM is 11,340
1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14 = 140
Simple, write it like you say it: 7 = x (140) 7 = 140x ---- ----- 140 140 x=0.05 (5%) Answer: 0.05 (5%)
140 28 x 5 = 140 = 35 x 4
