Find the least common denominator of 2 and 3, which is 6. Because you had to multiply 2 by 3 to get 6, you have to multiply 1 by 3, you then get 3/6. Because you had to multiply 3 by 2 to get 6, you have to multiply 1 by 2, you then get 2/6. Now, you can subtract 3/6 - 2/6, which equals 1/6. Hope this helps!
60% of the total (30) can swim
60% of 30 = (60/100)*30 = 0.60*30 = 18
So 18 children can swim
This means 30-18 = 12 cannot swim
---------------------------------------------------------
An alternative is to do it this way:
We know 60% can swim so that means 40% cannot swim.
Notice how 100% - 60% = 40%
Or in other words, the 60% and 40% add to 100%. This is because we have two choices: either the person can swim or cannot swim
Since 40% cannot swim, this means
40% of 30 = (40/100)*30 = 0.40*30 = 12
and we get the same result as before
---------------------------------------------------------
Final Answer: 12

90 sides give us 90 angles
sum of all inside angels is (n-2) * 180 deg. where n is number of angels
so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.
measure of exterior angle is 360 - 176 = 184 deg.
