Manny owns a home with a front and back lawn. The front lawn is ⅓ the size of the back lawn. If she mows ½ of her front lawn and ⅔ of her back lawn, what fraction of her entire lawn was left unmowed?

Respuesta :

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

The computation of the fraction of her overall lawn remaining unmowed is shown below:

Let us assume that the back lawn be x

So the front lawn would be

[tex]= \frac{1}{3}\times x\\\\ = \frac{x}{3}[/tex]

So, the total lawn is  ................... (i)

[tex]= x + \frac{x}{3}\\\\ = \frac{4x}{3}[/tex]

The back lawn mowed is [tex]\frac{2x}{3}[/tex]

Front lawn moved is [tex]\frac{x}{6}[/tex]

So, the total mowed is ....................(ii)

[tex]= \frac{2x}{3} + \frac{x}{6}\\\\ = \frac{5x}{6}[/tex]

So, the total unmowed is

[tex]= \frac{4x}{3} - \frac{5x}{6} \\\\= \frac{x}{2}[/tex]

Now the fraction is

[tex]= \frac{x}{2} \times \frac{3}{4x} \\\\ = \frac{3}{8}[/tex]

The fraction of the entire lawn unmoved is 3 / 8

What is a fraction?

The fraction is defined as the division of the whole part into an equal number of parts. The computation of the fraction of her overall lawn remaining unmowed is shown below:

Let us assume that the back lawn is x

So the front lawn would be

[tex]=\dfrac{1}{3}\times x[/tex]

[tex]=\dfrac{4x}{3}[/tex]

So, the total lawn is  ................... (i)

[tex]=x+\dfrac{x}{3}[/tex]

The back lawn mowed is

The front lawn moved is

So, the total mowed is ....................(ii)

[tex]=\dfrac{2x}{3}+\dfrac{x}{6}[/tex]

[tex]=\dfrac{5x}{6}[/tex]

So, the total unmowed is

[tex]=\dfrac{4x}{3}-\dfrac{5x}{6}[/tex]

[tex]=\dfrac{x}{2}[/tex]

Now the fraction is

[tex]=\dfrac{x}{2}\times \dfrac{3}{4x}[/tex]

[tex]=\dfrac{3}{8}[/tex]

Therefore the fraction of the entire lawn unmoved is 3 / 8
