hram777 [196]

Answer:

She needs to buy 3 such containers.

Step-by-step explanation:

Mrs. Saledo wants to buy $1\frac{1}{2}$ quarts of whipping cream.

Now, $1\frac{1}{2}$ quarts = $\frac{3}{2}$ quarts = $\frac{3}{2} \times 2 = 3$ pints.

Since we know that 1 US liquid quart = 1 US liquid pints.

If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )
