Question

Rob’s tablet is fully charged, he uses 1/12 of the charge playing games, 5/12 of the charge reading, and 3/12 completing homework. What fraction of the charge remains on rob’s tablet?

Answer 1

If you add it all up it's 9/12 and minus it but 12/12 it equals 3/12 so 3/12 of the tablets power is left.

Answer 2

so we just add up since all of the numbers denomonater is 12
1/12+5/12=6/12
now 6/12+3/12=8/12
do not forget to simpify
8/12= 2/3
