No, 1 5th is 1/5 = 0.2. 10 20ths is 10/20 = 0/5 (or a half).
10 50/5 =5
you add exponents in a case like 1 to the 5th (to the 5th is your exponent of 5) So 1 to the 5th + 1 to the 9th. you would just add your exponents. so 9+1=10 so you answer would be 1 to the 10th. this is only when you have 2 of the same base number, in this case, your base number is 1
Yes, it is. To solve it: The numerator is the number on top. In this case you have a 1 and a 3 The denominator is the number on the bottom. In this case you have a 5 and a 10 You want the denominators to be equal. To do this, find the lowest number that both divide into (in this case 10, 10/5 = 2 and 10/10 = 1) To get the denominator of the 1/5th fraction to equal 10, you multiply (x) by 2. This will give you 10, however whatever you do to the top, you have to do to the bottom - i.e. you times the 5 by two (the denominator), you need to times the 1 by two (the numerator) this gives you 2/10ths = 1/5th. The second one is easier = to make 10 = 10, you only have to times by 1, so nothing changes. This means that you are seeing if 2/10ths is less than 3/10ths. As you have 1 less tenth, it is obvious that it is less. So 1/5th (or 2/10ths) is less than 3/10ths.
It is: 1/5 of 50 is 10

10th to the 5th power = (1/10) to the fifth power = (1/10)5 = (1/10)*(1/10)*(1/10)*(1/10)*(1/10) = 1/100,000 or 0.00001
2/10
No, 1 5th is 1/5 = 0.2. 10 20ths is 10/20 = 0/5 (or a half).
10 50/5 =5
No. 1/5 is equal to 2/10
5/10 as a fraction is 1/2.
3/5 = 6/10, 1/10 larger than 1/2
77/10 or 7.7
105 * 107 = 1012 = 1 trillion
6/5 x 10/3 = 4
