Daniel practiced his new dance moves 30 minutes on Monday and again on Tuesday. At the end of one week, how many minutes would he have practiced?

##60color(white)(i)"minutes"##

If Daniel practiced his new dance moves on Monday and Tuesday for ##30## minutes on each day, then he danced for two days. Since you know he danced for ##30## minutes for each day, multiply "##30## minutes per day" by "##2## days" to determine the total number of minutes he danced for.

Thus:

##2color(white)(i)"days"xx(30color(white)(i)"minutes")/"day"##

##=2color(white)(i)color(red)cancelcolor(black)("days")xx(30color(white)(i)"minutes")/color(red)cancelcolor(black)("day")##

##=2xx30color(white)(i)"minutes"##

##=color(green)(|bar(ul(color(white)(a/a)60color(white)(i)"minutes"color(white)(a/a)|)))##

##:.##, he would have practiced for ##60color(white)(i)"minutes"##.
