`3/5:0,5+3/4:0,25=3/5xx2+3/4xx4=6/5+3=6/5+15/5=21/2`
0,6 : 0,5 + 0,75 : 0,25
= 1,2 + 3
= 4,2
\(=\dfrac{3}{5}:\dfrac{1}{2}+\dfrac{3}{4}:\dfrac{1}{4}=\dfrac{6}{5}+\dfrac{3}{1}=\dfrac{6}{5}+\dfrac{15}{5}=\dfrac{21}{5}\)
`3/5 : 0,5 + 3/4: 0,25`
`= 6/5+3`
`= 21/5`
3/5 : 0,5 + 3/4: 0,25
=6/5 + 3 =6/5 + 15/5=21/5
