Janie skates at the local skating rink for about 2.4 hours every day. If the skating rink is open 54 days a year, about how many
hours does Janie skate each year?
2 answers:
Well, if she skates about 2.4 hours EVERY day and it's open 54 days you multiply the number of hrs and the number of days.
So, now we have our equation; 2.4×54=?
Now we multiply and "pretend" that the decimal isn't there... which gives us 1,296
Now we remember how many decimal places we had and bring it over to our answer.
Now we have 129.6
So... 54×2.4=129.6
About 129.6 hours every single year
