Answer:because i know
Step-by-step explanation:
the first 2
3 squares = 4 circles, so (number of squares)/(number of circles) = 3/4.
3/4 = 12/16
:::::
4 squares = 2 circles, so (number of squares)/(number of circles) = 4/2.
4/2 = 2/1
:::::
2 squares = 5 circles, so (number of squares)/(number of circles) = 2/5.
2/5 = 4/10
20 times 5 is 100. We can multiply 2*5 and get 10, then add another zero to make it easier.
