$7 \frac{1}{2}$ pounds or $7$ pounds $8$ ounces.

#### Explanation:

If you are to make $40$ tarts, you will need $40$ times as much flour as for $1$ tart.

$40 \times 3 = 120$ ounces

Now you need to find out how many pounds that is.
There are $16$ ounces to a pound.

$120 \div 16 = 7 \frac{1}{2}$

You will need $7 \frac{1}{2}$ pounds, or $7$ pounds $8$ ounces
