a) 3/8 liczby 18 = 3/8 * 18 = 27/4 = 6 3/4
b) 2 1/3 wartości 300 zł = 7/3 * 300 = 700
c) 5 2/7 kwoty 700 zł = 37/7 * 700 = 3700
= - 120 - 57 i 3/5=
= - 177 i 3/5
a)
3/8 liczby 18
3/8 * 18 = (skracam 8 z 18)
= 3/4 * 9=
= 27/4 =
= 6 i 3/4
b)
2 i 1/3 wartości 300 zł
2 i 1/3 * 300 zł =
= 7/3 * 300 zł = ( skracam 3 z 300)
= 7/1 * 100 zł =
= 700/1 zł =
= 700 zł
c)
5 i 2/7 kwoty 700 zł
5 i 2/7 * 700 zł =
= 37/7 * 700 zł = (skracam 7 z 700)
= 37/1 * 100 zł =
= 3 700 zł
