Question

Oblicz 60% liczby a wiedząc ,że a =1 2/3:(0,5)^2-2 5/6.

Answer 1

A =(1 i 2/3):(0,5)^2-(2 i 5/6)
a=(5/3):(1/2)^2-(17/6)
a=(5/3):(1/4)-(17/6)
a=(5/3)*(4/1)-(17/6)
a=(20/3)-(17/6)
a=(40/6)-(17/6)
a=(23/6)=3 i 5/6

60%=60/100=6/10=3/5

60% z (3 i 5/6) to
(60/100)*(3 i 5/6)=(3/5)*(23/6)=23/10=2,3
