Well first you have to divide 25 by 15 to get the decimal equivalent 1.6 with the 6 repeating. To get the percent all you have to do is multiply the decimal equivalent by 100 to get 166 and 2/3 %.
You take however many times the denominator goes into the numerator as a whole number. For example, 6/2 would be 3. Then take the remaining fraction and turn it into a decimal. For example, 7/2 would be 3 and 1/2 left over or 3.5. Just take the whole number and turn the fraction left over into a decimal add-on
0.22/10 = .2
6/78819 rounded to 2 decimal places is 6.79.
Well you firstly you turn it into a decimal e.g 1/2=0.5 and then you multiply the decimal by 100 e.g 0.5=50%. So that's how you do it 1/2=50%
2/3 = 0.66666 repeating
Well, as a decimal 2/4 is 0.5, which also equals 4/8, which reduces to 3/6, which in turn reduces to 2/4, finally resulting in 1/2.
11000 in base 2 is 24 in decimal. 110 in base 2 is 6 in decimal. 24 - 6 is 18. In base 2 18 is 10010.
2.83333 recurring The 2 is the 2. 5 divided by 6 is 0.83333
6/12=1/2=0.5
It is equal because when you turn a decimal into a percent you move the decimal 2 to the right.
