olganol [36]

Answer:

Lily babysit for less than 4 hours.

Step-by-step explanation:

Given:

Lucy spends in a week babysitting for 4 hours.

Lily spends seven-eighths of 4 hours.

Now, to find whether Lily babysit for more than 4 hours or less than that.

Number of hours Lucy babysit = 4 hours.

So, to get the hours Lily babysit:

$\frac{7}{8}\ of\ 4\ hours.$

$=\frac{7}{8}\times 4\\\\=\frac{28}{8} \\\\$

On simplifying we get:

$=\frac{7}{2} \\\\=3\frac{1}{2}\ hours.$

Thus, Lily spends $3\frac{1}{2}\ hours$ for babysitting which is less than 4 hours.

Therefore, Lily babysit for less than 4 hours.
