[tex]\rightarrow \sf \dfrac{3}{4} - \dfrac{1}{5}[/tex]

make the denominators same by lcm

[tex]\rightarrow \sf \dfrac{5(3)}{20} - \dfrac{4(1)}{20}[/tex]

expand the following

[tex]\rightarrow \sf \dfrac{15}{20} - \dfrac{4}{20}[/tex]

Join the fractions together

[tex]\rightarrow \sf \dfrac{15-4}{20}[/tex]

Answer:

11/20 or 0 whole 11/20 or 0.55

Step-by-step explanation:

  • [tex]3/4 - 1/5[/tex]

Find the least common multiple (LCM) of 4 and 5 at first:

We can't do the LCM of 5 and 4,so just multiply them, 5*4 = 20

Now,

For 3/4 : divide 20 by 4,then multiply the result by 3.For 1/5 : divide 20 by 4, then multiply the result by 1. Simple!

  • [tex] \cfrac{15 - 4}{20} [/tex]

Subtracting the numerators,

  • [tex] \boxed{\cfrac{11}{20} }[/tex]

As a whole number:

  • [tex]\boxed{0 \cfrac{11}{20} }[/tex]

As a decimal:

  • [tex]\boxed{0.55 }[/tex]
