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

Answer:
4080 ft
Step-by-step explanation:
34 yards of ribbon are used to prepare 8 teddy bears. The yards of ribbon used to prepare 320 teddy bears are:
320 teddy bear × (34 yard/8 teddy bear) = 1360 yard
1 yard is equal to 3 feet. The feet corresponding to 1360 yards is:
1360 yard × (3 feet/1 yard) = 4080 feet
