The awnwer is easy. It =55. Because you add the 1,2,3,4,5,6,7,8,9and the 10 together and you get 55. You forget about the timesing because it is not a squared number.
2/5 - 1/10 = (2×2)/(5×2) - 1/10 = 4/10 - 1/10 = (4-1)/10 = 3/10.
1/5 one tenth of 2:= 1/10 of 2= 1/10 * 2= 1/10 * 2/1= 2/10 or 1/5
Use the following [Euro]cent coins: 10 + 5 + 1 10 + 2 + 2 + 2 10 + 2 + 2 + 1 + 1 10 + 2 + 1 + 1 + 1 + 1 10 + 1 + 1 + 1 + 1 + 1 +1 5 + 5 + 5 +1 5 + 5 + 2 + 2 + 2 etc.
1/10 + 2/5 = 1/10 + 4/10 = 5/10 = 1/2
1/10 - 2/10 = -1/10

√100 = (100)^(1/2) = (10^2)^(1/2) = 10^[(2)(1/2)] = 10^(2/2) = 10^1 = 10
2/5 - 1/10 = (2×2)/(5×2) - 1/10 = 4/10 - 1/10 = (4-1)/10 = 3/10.
It is 2 + 0.2 + 0.05
1/5 one tenth of 2:= 1/10 of 2= 1/10 * 2= 1/10 * 2/1= 2/10 or 1/5
The factors of 1530 are 1, 2, 3, 5, 6, 9, 10, 15, 17, 18, 30, 34, 45, 51, 85, 90, 102, 153, 170, 255, 306, 510, 765, 1530. For them to be common, they need to be compared to another set of factors.

2: 1, and 2 10: 1, 2, 5, and 10
2 1/10:= 2 + (1 ÷ 10)= 2 + 0.10= 2.1
The product of 1, 2 and 5 is 10.The product of 1, 2 and 5 is 10.The product of 1, 2 and 5 is 10.The product of 1, 2 and 5 is 10.
1/5 - 1/10 = 2/10 - 1/10 = (2 - 1)/10 = 1/10
