Simplify the expression below. \(7\frac{\mathrm{1} }{\mathrm{4}} \times \frac{\mathrm{1} }{\mathrm{18}} \)
Which of the following is CORRECT?

Multiply the whole number by the denominator.
Add the answer from step 1 to the numerator.
Write the answer from step 2 above the denominator.
\(7 \times 4+1 = 29 \longrightarrow \frac{\mathrm{29} }{\mathrm{4} } \)
To multiply fractions simply multiply across the top and the bottom: \(\frac{\mathrm{29} }{\mathrm{4}} \times \frac{\mathrm{1} }{\mathrm{18}}= \frac{\mathrm{29} }{\mathrm{72}} \)
