Zadanie 1
a) 5 + x = suma liczby 5 z liczbą x
b) 4c = iloczyn liczb 4 i c
c) a^{2} = a do kwadratu
Zadanie 2
\frac{1}{2} a + x = \frac{1}{2} * 6 + 4 = 3 + 4 = 7
Zadanie 3
P = 4 cm * 1 \frac{1}{4} cm= \frac{4}{1} cm * \frac{5}{4} cm = \frac{1}{1} cm * \frac{5}{1} cm = 5 cm^{2}
Zadanie 4
a) a - 1 \frac{3}{4} = 2 \frac{1}{2}
a = 1 \frac{3}{4} + 2 \frac{1}{2} = 1 \frac{3}{4} + 2 \frac{2}{4} = 4 \frac{1}{4}
a = 4 \frac{1}{4}
b) x : 6 = 1 \frac{2}{3}
x = 6 * 1 \frac{2}{3} = 10
x = 10
