3.695 to 4 name the place value to which each number was rounded

3.695 was rounded to the nearest thousandths and 4 is rounded to the nearest ones place. Hope that helped :)

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

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
