On saturday, percy biked for 6 3/12 hours. on sunday, he biked 5 2/3 hours. which is the quickest strategy percy can use to find the least common denominator, so he can add the hours he biked over the weekend?

make 3/12 1/4 and make 2/3 4/6 then find the lcm of those number

6 3/12+5 2/3=11 3/12+8/12=11 11/12
