a)
[tex] \frac{1}{2} + 1.5 = 0.5 + 1.5 = 2[/tex]
b)
[tex] \frac{1}{2} - 0.25 = 0.5 - 0.25 = 0.25[/tex]
c)
[tex]3.5 - 2 \frac{1}{2} = 3 \frac{1}{2} - 2 \frac{1}{2} = 1[/tex]
d)
[tex] \frac{3}{4} + 0.25 = \frac{3}{4} + \frac{1}{4} = \frac{4}{4} = 1[/tex]
e)
[tex]1 \frac{1}{2} - 1.5 = 1.5 - 1.5 = 0[/tex]
f)
[tex]1.5 - 1 \frac{1}{4} = 1.5 - 1.25 = 0.25[/tex]
Myślę że pomogłem ;)
