Take your pick; 10 and 20, 10 and 30, 10 and 40, 10 and 50, 10 and 60, 10 and 70, 10 and 80, 10 and 90, 20 and 30, 20 and 50, 20 and 70, 20 and 90, 30 and 40, 30 and 50, 30 and 70, 30 and 80, 40 and 50, 40 and 70, 40 and 90, 50 and 60, 50 and 70, 50 and 80 50 and 90, 60 and 70, 70 and 80, 70 and 90, 80 and 90.
The GCF of 30 and 70, evidently, is 10 (both end in 0). Therefore, the LCM is 30/10 * 70/10 * 10 = 3 * 7 * 10 = 210.
To work out 30% of 70 Work out 10% by dividing 70 by 10 This gives you 7 You then times this by 3 because 100%=70 10%=7 30%=21 It's simple after you understand the concept :)

30/0.5 + 10 = 70
The GCF of 30, 50, and 70 is 10.
30% of 70 is 21 because 10% is 7
The answer is 70 (30 / 0.5 = 60, 60 + 10 = 70)
