2 1 4 was subtracted twice from a number; then 1 8 was subtracted three times and 2 3 was subtracted twice. The resulting number is 3 11 24 . Find the number

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
