Step-by-step explanation:
7/20
=0.35
35%
=35/100
=0.35
Hence, 7/20=35%
I can use a chart by numbers them on the chart because I think 4 should be after the 3
DECA=10, decagon = 10 sides.
since each side is 1.8 long, all 10 sides will be 10*1.8 or 18 units long, so that'd be the perimeter then,
There are 25 boxes and 15 of them are shaded.
15/25 = 0.6 = 60%
The answer isnt 7 thats forsure
