Yolanda spends 82/3 hours per month playing soccer. Approximately how many hours does she play soccer in a year?
Vesnalui [34]
328 because 82/3 multiplied by 12 is 328 and you do that because there's 12 months in a year and if you spend 82/3 hours per month playing soccer than you would multiply that by 12 which gives you 328 hours.

It is also a square meaning all sides are equal
So with this is mind we can ask the question what times what equals 16 and is the same number
This would be 4 since 4 times 4 is sixteen
