Here hope this helps A pie or circle is a 100% So if you add all of the presents of milks you get 100 and half of 100 is 50 so you cut the circle in half. Then 30 is bigger then 20 but only by 10% so you make 30 just a little bigger then 20.
Hope I helped you! If so please give me brainiest. If not please say what I did wrong. Thank you. Have a nice day!
P.s. My notifications for brainy it’s glitching so I won’t see any comments for this so if you have any further questions I can’t help you. sorry!!! - Pam Pam
