Can someone help me out? This is really hard! (brainliest if it's correct!)

Step-by-step explanation:

Lets convert the time she spend working into a improper fraction.

[tex]4 \frac{1}{2} = \frac{4 \times 2 + 1}{2} \\ = \frac{9}{2} hours[/tex]

Since she spend 2/5 of the above time mowing lawns,

Time Spend mowing lawns =

[tex] \frac{2}{5} \times \frac{9}{2} \\ = \frac{2 \times 9}{5 \times 2} \\ = \frac{18}{10} hours \\ = \frac{18 \div 2}{10 \div 2} \\ = \frac{9}{5} hours \\ = 1 \frac{4}{5} hours \: or \: 1.8 \: hours[/tex]
