Question

Cathrine uses 6 ounces of butter for preparing cream for one cake. How many pounds of butter she needs to make cream for 25 cakes ?

• A. $10$ pounds
• B. $9.375$ pounds
• C. $7.539$ pounds
• D. $5.337$ pounds

Answer 1

The correct option is B $9.375$ pounds

Butter used by cathrine to make cream for $1$ cake = $6$ ounces
So,
Butter to be used to make cream for $25$ cake $=25\times 6=150$ ounces

we know that,
$1$ pound $=16$ ounces
Or,
$1$ ounce =$\frac{1}{16}$ pounds
$\Rightarrow 150$ ounces $=\frac{150}{16}=9.375$ pounds.

Hence, Catherine needs $9.375$ pounds of butter to prepare cream for $25$ cakes.
