Question

if you get 1 dollar every 2 week how many weeks will it take to get 800 dollars

Answer 1

Step 1 ) Apply numbers into fraction form. Include variables to represent numerator and denominator.

$\displaystyle\frac{2w}{1d}$

Note: w = week; d = dollars

Step 2 ) Multiply both sides by 800 to change 1d into 800d.

$\displaystyle\frac{2w}{1d}$

$\displaystyle\frac{2w}{1d} * \frac{800}{800}$

$\displaystyle\frac{1,600w}{800d}$

This means that the amount of weeks it'll take to reach 800 dollars is...

1,600 weeks.
