49.Change the quantity to the indicated unit. 60 in= blank ft

Answer 1

2.345 to the nearest whole # would be 2.

6/42 can be reduced to 1/7.

Find the change: It's $200-$158 = $42 (the difference). This difference is a decrease of $42. The percentage decrease would then be [$42/$200]*100%, or 21%. You don't have to use the " - " symbol because the word "decrease" takes care of that.
