Question

Hey y’all I need this answer quickly!!! 3/4 - 1/5

Answer 1

Answer:

$\sf \dfrac{11}{20} \quad or \quad 0.55$

Explanation:

$\rightarrow \sf \dfrac{3}{4} - \dfrac{1}{5}$

make the denominators same by lcm

$\rightarrow \sf \dfrac{5(3)}{20} - \dfrac{4(1)}{20}$

expand the following

$\rightarrow \sf \dfrac{15}{20} - \dfrac{4}{20}$

Join the fractions together

$\rightarrow \sf \dfrac{15-4}{20}$

Subtract the integers

$\rightarrow \sf \dfrac{11}{20} \quad or \quad 0.55$

Answer 2

Answer:

11/20 or 0 whole 11/20 or 0.55

Step-by-step explanation:

• $3/4 - 1/5$

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!

• $\cfrac{15 - 4}{20}$

Subtracting the numerators,

• $\boxed{\cfrac{11}{20} }$

As a whole number:

• $\boxed{0 \cfrac{11}{20} }$

As a decimal:

• $\boxed{0.55 }$
