Question

Oblicz !!! 2/5-1 1/3+3,5-(-2)= 0,25:1 1/2-(-4 1/2)= 1 1/3-3/4:2 1/2= 4 2/5-3,4:2 1/2= Np:1/3 to inaczej jedna trzecia .a 1 1/3 to inaczej jeden i jedna trzecia

Answer 1

1.2/5-1=2/5-5/5=-3/5

2. 1/3+3,5-(-2)=1/3+3 i 1/2+2=1/3+5i1/2=2/6+5 i3/6=5i 5/6

3. 0,25:1=0,25

4.1/2-(-4 1/2)=1/2+4i 1/2=4i 2/2=5

5. 1 1/3-3/4:2 1/2=1 i 1/3-3/4*5/2=1i 20/30

6.4 2/5-3,4:2 1/2=4 i 2/5 - 34/10 *2/5=4 i2/5- 4/25=4 i 10/25-4/25= 4 i 6/25

Answer 2

2/5-1i1/3+3,5+2=6/15-1i5/15+5,5=-15/15+5,5=-1+5,5=4,5

1/4:3/2+4i1/2=1/4*2/3+4i1/2=1/6+4i3/6=4i4/6=4i2/3

1i1/3-3/4:5/2=1i1/3-3/4*2/5=1i1/3-3/10=1i10/30-9/30=1i1/30

4i2/5-3,4:5/2=4i2/5-34/10*2/5=4i2/5-34/25=4i10/25-34/25=3i1/25
