A woman earns $450 a month. She pays 1/5 of this amount for rent, 1/3 of this amount for food and 1/6 for other household expenses. The amount of money she has left per month is:

To find out how much the woman pays for rent, we need to multiply her monthly earnings ($450) by the fraction 1/5:

$450 x 1/5 = $90

So she pays $90 for rent.

To find out how much she pays for food, we need to multiply her monthly earnings ($450) by the fraction 1/3:

$450 x 1/3 = $150

So she pays $150 for food.

To find out how much she pays for other household expenses, we need to multiply her monthly earnings ($450) by the fraction 1/6:

$450 x 1/6 = $75

So she pays $75 for other household expenses.

To find out how much money she has left per month, we need to subtract the total amount she pays for rent, food, and other household expenses from her monthly earnings:

$450 - $90 - $150 - $75 = $135

Therefore, the woman has $135 left per month after paying for rent, food, and other household expenses.

To find out the amount of money the woman has left per month, we need to subtract the expenses from her monthly earnings.

First, let's calculate the amount she pays for rent:
Rent = (1/5) * $450 = $90

Next, let's calculate the amount she pays for food:
Food = (1/3) * $450 = $150

Finally, let's calculate the amount she pays for other household expenses:
Other expenses = (1/6) * $450 = $75

Now, let's subtract the sum of all expenses from her monthly earnings to find out how much money she has left:
Amount left = Earnings - (Rent + Food + Other expenses)
Amount left = $450 - ($90 + $150 + $75)
Amount left = $450 - $315
Amount left = $135

So, the woman has $135 left per month after paying all the expenses.
