    2/5=0.4 you need just to solve \[(0.4\div100)x=0.9 \implies x=0.9\div(0.4\div100) \implies x=225\]

    finding the percent of change. Round to the nearest tenth of a percent if possible. 1.) The price of a calculator went from $20 last year to $18 this year. What is the percent change this year?

    okay.. you just need to do the following; (18-20)/20=-1/10 then multiply the number by 100% (-1/10)*100%= -10%

    you should try it.. follow the same steps of the previous one: (old price-new price)/old price.. and then multiply by 100%
