Nie ogarniam:)
Zadanie w załączniku:)
P.S. to jest mega trudne, całą lekcje jedno zadanie robiliśmy. ;p
a)
733 - 100%
x - 65,9%
x = 733*65,9/100 = 48304,7/100 = 483,047mln ~~ 483 mln
6641 - 100%
x - 60,6%
x = 6641*60,6/100 = 402444,6/100 = 4024,446mln~~4024 mln
b)
x - 11,4%
x = 6641*11,4/100 = 75707,4/100 = 757,074~~757mln
757mln>733mln odp. więcej.
c)
2007r - 757 mln
x-19,9%
x = 733*19,9/100 = 14586,7/100 = 145,867 ~~146mln
(733-146)/146 = 587/146 = 4,0205~~4,02
4,02*100% = 402%
d)
733-100%
x-0,2%
x = 733*0,2/100 = 146,6/100 = 1,466~~1mln
6641-100%
x-5,1%
x = 6641*5,1/100 = 338696,1-100 = 3386,961~~3387mln
3387:1 = 3387mln
