Step-by-step explanation:
60
Because 60 can be divided by all three of them, and it is the lowest one possible, 30 doesn't work because 30 divided by 12 is 2.5, and that isn't a whole number
Both recipes would add up to 1 5/12 this is using the black widow way
There are 12 girls.
To find this, you must first find how many spectators are adults. Multiply 600 by 80% (0.80) to get 480. Then subtract 480 from 600 to get the number of children (120).
Since it asks to find how many girls there are, we multiply 10% (0.10) to 120. This will give you a final answer of 12 girls.
I hope this helps!
