Sagot :

Answer:

Ok so 5 and tens least common denominator is 10. So 6/10- 2/10 (1/5×2=2/10)= 4/10. so now take 4/10 and 1/4 and find the lcm Which is 20 so 4/10×2 is 8/20+10/20=

18/20

[tex]\\ \sf\longmapsto \dfrac{6}{10}-\dfrac{1}{5}+\dfrac{1}{4}[/tex]

[tex]\\ \sf\longmapsto \dfrac{2-4+5}{20}[/tex]

[tex]\\ \sf\longmapsto \dfrac{-2+5}{20}[/tex]

[tex]\\ \sf\longmapsto \dfrac{3}{20}[/tex]
