Question

Multiply and express the answer as a mixed fraction:
$7 \times 2\dfrac{1}{4}$.

Answer 1

Hint – In order to solve this problem we need to know that a term is in mixed fraction like $a\dfrac{b}{c}$ can be written as $\dfrac{{ac + b}}{c}$. Doing this will solve your problem.

Complete step-by-step answer:
The given equation is $7 \times 2\dfrac{1}{4}$.
As we know that $a\dfrac{b}{c}$= $\dfrac{{ac + b}}{c}$.
So, $7 \times 2\dfrac{1}{4} = 7 \times \dfrac{{8 + 1}}{4} = \dfrac{{63}}{4}$
And $\dfrac{{63}}{4}$in mixed fraction can be written as $15\dfrac{3}{4}$.
Hence the answer is $15\dfrac{3}{4}$.

Note – Whenever you face such types of problems you just need to know that the term $a\dfrac{b}{c}$ is nothing but $\dfrac{{ac + b}}{c}$. A Mixed Fraction is a whole number and a proper fraction combined. This information will solve your problem.
