Question

oblicz: 4,4:4+1/4= 2/5:(2*0,5)= 2/3*6:1/4= (0,5+1/2)*2= 7,2-1/8*24= pilnie prosze o pomoc :)

Answer 1

4,4:4+1/4=16/10*2 * 1/4*5 + 0,25=32/20*5/20+0,25=160/20+0,25=8+0,25=8,25

 

2/5:(2*0,5)=2/5*1/1*5=2/5*5/5=10/5=2

 

2/3*6:1/4=2/3*2*1/6:1/4=4/6*1/6:1/4=4/6*4/1*6=4/6*24/6=96/6=16

 

(0,5+1/2)*2=1*2=2  <-- ona ma was za idiotów?

 

7,2-1/8*24=7,2-1/8*3*24=72/10-3/24*1/24=72/10*8-1/8*10=579/80-10/80=566/80=7  3/40
