Question

Solve for n.

Answer 1

$\frac{4}{44} =\frac{1\times4}{11\times 4}= \frac{1}{11} = \frac{1\times 7}{11\times 7} = \frac{7}{77}\\\\n= 7$

Your answer is B.

Another way to solve it is by cross multiplying.

$\frac{4}{44} = \frac{n}{77}\\\\4 \times 77 = 44n\\\\n = \frac{4\times 77}{44}\\\\n = 7$

Answer is B.
