Question

Find the percent of change. Round to the nearest tenth of a percent if necessary. 3/8 to 7/8

1 Answer

  • remember (a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)

    percent change=change/original

    change=7/8-3/8=4/8=1/2


    change/orignal=(1/2)/(3/8)=(1/2)(8/3)=8/6=4/3=1 and 1/3=1.33333
    percent means parts out of 100
    1.333333/1=13.3333/10=133.333333/100=133.33333%


    answer is 133.3% (rounded)
