b) 2% wynosi 8
c) 4% wynosi 6
d) 5% wynosi 12
e) 10% wynosi 170
f) 75% wynosi 24

Answer 1

17 - 1%
x - 100%
x = (17×100%)÷1%=700

8 - 2%
x - 100%
x = (8×100%)÷2%=400

6 - 4%
x - 100%
x = (6×100%)÷4%=150

12 - 5%
x - 100%
x = (12×100%)÷5%=24

170 - 10%
x - 100%
x = (170×100%)÷10%=1700

24 - 75%
x - 100%
x = (24×100%)÷75%=32

Answer 2

A) 0,01x=17 x=17:0,01=1700
