Question

Ross went to grocery store to buy wheat flour. He wants to buy $4.5$ pounds of flour but the measuring device measures weight only in ounces. Can you help Ross in the calculating the correct reading of measuring device?

• A. $64$ ounces
• B. $72$ ounces
• C. $80$ ounces
• D. $36$ ounces

Answer 1

The correct option is B $72$ ounces

Given that Ross wants to buy $4.5$ pounds of flour.
But, the measuring device measures weight only in ounces.
So, we have to do conversion of units i.e. converting pounds into ounces.
We know,
$1$ pound $=16$ ounces
So,
$4.5$ pounds $=4.5\times 16=72$ ounces.

Hence, $72$ ounces will be the correct reading of the measuring device.
