Step-by-step explanation: First, I did 3 x 1/4 (3/4) and with 3/4, I used the denominator (4) and multiplied both the numerator and denominator (with this I used 1/3) and multiplied 3 x 4 and 1 x 4 and got 4/12. Now I take the denominator of 3 (from 1/3) and multiply the numerator and denominator from the 3/4, and 3 x 3 and 3 x 4 which got me 9/12. Lastly, I did 9/12 and 4/12 and got 13/12 which is just 1 1/12
If 50% of the price is $285, all you have to do is mulipy 285 by 2. This would give you the answer of $570 as the orignal price of the washing machine.
