Question

The value of $12\frac{1}{2}\times 8\frac{1}{3}$ calculated using binomial multiplication is

• A. $94\frac{1}{6}$
• B. $108\frac{1}{6}$
• C. $104\frac{1}{6}$
• D. $96\frac{1}{6}$

Answer 1

The correct option is C

$104\frac{1}{6}$

$12\frac{1}{2}\times 8\frac{1}{3}$ can be written as

$(12+\frac{1}{2})(8+\frac{1}{3})$

$=12\times 8+12\times \frac{1}{3}+\frac{1}{2}\times 8+\frac{1}{2}\times \frac{1}{3}$

$=96+4+4+\frac{1}{6}$

$=104\frac{1}{6}$
