Karla spent 1/12 of the day cleaning. then spent 1/4 of the day playing. what fraction of the day was karla not cleaning or playing?

Find a common denominator
1/4=3/12
Then add the fractions
1/12+3/12=4/12=1/3
Then subtract from one full day
1-1/3=2/3

One day is equal to 24 hours

so you 1/12 multiplied by 2 which is 2/24, so she spent 2/24 of the day cleaning

So you multiply 1/4 by 6 which is 6/24, so she spent 6/24 of the day playing

So 6+2 is 8 which is 8/24

So 24-8 is 16

So therefore Karla spent 16 hours not cleaning or playing

Hope this helps xx
