You can put this solution on YOUR website!

If we had 100 people total, then 45% of that would be 45 children. The term "percent" means "per 100" or "for every 100".

So we can have this ratio
45 children: 100 people total

Multiply both parts of that ratio by 6 so that the "100 people" turns into "600 people"
45 children: 100 people total
6*45 children: 6*100 people total
270 children: 600 people total

There are 270 children that visited the museum on Tuesday

A more conventional approach is to use your calculator
45% of 600 = (45/100)*600
45% of 600 = 0.45*600
45% of 600 = 270
yielding the same answer
