The equivalent fraction of 9/15 would be 3/5.
She saves 10 per week.......after 4 weeks, she had 90
so if she started with nothing, after 4 weeks she would have 40.....but for her to have 90, she would have had to have started with (90 - 40) = 50.
Think about it....she starts with 50....and then saves 10 for 4 weeks giving her 40......and now she has 40 + 50 = 90
so ur answer is : Roberta had $ 50 before she started to save money each week
38 i think it means infinite
3.21 it should be at least
Answer:
37 %
Step-by-step explanation:
here..
only Dog = 20- 5 - 4 - 1 = 10
only goats = 30 - 5 - 3 - 1 = 21
only cattle = 40 - 4 - 3 - 1 = 32
then ... since the maximum percentage is 100 %
people who don't own any animal = 100% - 10% - 21% - 32% = 37 %
