    Step-by-step explanation:

    so let put into fraction

    george=⅓

    Al=1/5

    so ⅓+1/5=8/15 (as both denominator will be 15 by X5 and X3)

    We want to know how many hours they have to mow in order to mow 1 lawn.

    This can be represented by the equation: (8/15) * x=1

    To solve for x, we would divide both sides by 8/15. This leaves us with x=15/8 which is 1.875.

    If you would like this answer in hours and minutes, covert the. 875 to minutes by multiplying by 60.

    This gives you a final answer of about 1 hour and 53 minutes.
