Last year Johnny took 4.5 hours to put holiday lights on his house by himself. The following year, his wife, Amanda helped him. Together, it took them 2.88 hours to put the lights up. How long would Amanda take to put up the lights if she did it by herself?

1.26

Step-by-step explanation:

It might be 1.26 becuase it took Johnny 4.50 hours to do it by him self and now with help it took him 2.88. What I did was subtract 4.50 by 2.88 to see how much it took Johnny him self which I got 1.62. So if 1.62 is less than 2.88 there is still numbers left over so what i did was 2.88 minus 1.62 so I could get the remainding hours which would be the total amount of hours that Amanda did.

step-by-step explanation:

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
