Question

Hey y’all I need this answer quickly!!!

3/4 - 1/5

Answer 1

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 }`

Answer 2

`\sf (11)/(20) \quad or \quad 0.55`

Step-by-step explanation:

`\rightarrow \sf (3)/(4) - (1)/(5)`

make the denominators same by lcm

`\rightarrow \sf (5(3))/(20) - (4(1))/(20)`

expand the following

`\rightarrow \sf (15)/(20) - (4)/(20)`

Join the fractions together

`\rightarrow \sf (15-4)/(20)`

Subtract the integers

`\rightarrow \sf (11)/(20) \quad or \quad 0.55`
