1.Oblicz ile procent liczby 25 stanowi liczba 5.
2.Oblicz wartość wyrażenia:
2² · [0,4 - ⅖ : (-2)] + ½ - 5² · 5⁻¹ + 8⁰
1)
25 - 100%
5 - x%
500:25 = 20%
2)
4x (0.4- 0.4:1/2)+1/2 - 25 x 1/5 + 1 =
(1.6 - 1.6 - 2.0) + 1/2 - 0.5 + 1 =
(1.6- (-0.4)) +1/2 - 0.5 +1 =
2.0 + 0.5 -0.5+ 1 =
3
mam nadzieje, że pomogłem ;)
1. 5/25= 1/5= 20%
