Nora spent a total of 8 1/6 hours on community service last year. given that her visit to the old folks' home made up 4/7 of the total time on community service, find the amount of time she spend on visiting the old folks' homes.

That would be 8 1/6  * 4/7  =  49/6 * 4/7 =  7*4 / 6 =  28/6 = 4 4/6 = 4 2/3

Answer is 4 2/3 hours

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
