What is the answer to 7c 3 fl oz - 3c 4fl oz?

Answer 1

To solve the problem (7\text{c} , 3\text{fl oz} - 3\text{c} , 4\text{fl oz}), first convert the measurements to a common unit. This can be done by converting the fluid ounces into cups (since 1 cup = 8 fl oz):

• (3 \text{ fl oz} = \frac{3}{8} \text{c}) and
• (4 \text{ fl oz} = \frac{4}{8} \text{c} = \frac{1}{2} \text{c}).

Now, the equation becomes (7\text{c} + \frac{3}{8}\text{c} - 3\text{c} - \frac{1}{2}\text{c}).

Combining these gives (4\text{c} + \frac{3}{8}\text{c} - \frac{4}{8}\text{c} = 4\text{c} - \frac{1}{8}\text{c} = \frac{32}{8}\text{c} - \frac{1}{8}\text{c} = \frac{31}{8}\text{c}), resulting in (3 \text{c} , 7.5 \text{fl oz}) after converting back to cups and fluid ounces.
