1/10
To convert a percentage to a fraction, put it over 100 and reduce: 30 % = 30/100 = 3/10
First of all, percent means in "one hundred". So 30% is the same as 30/100, which we can reduce to 3/10 or 0.3. To figure out what 30% of 810 is, you simply multiply:3/10 x 810 = 2430/10And then divide:2430 / 10 = 243
Yes, because 3 is the only number that both can be divided by to further reduce both sides. 21/3 = 7, 30/3= 10 so, 21/30 = 7/10
No.
