Can u pls explain to me how to do this?

So basically you just have to count how many numbers there are, so there are 3 91’s so you would put a 3 in the box go 91 and there’s only 1 57 so you put a 1 in the box.

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
