What is the number value after the decimal point

If you are asking for the number value to the right of the decimal point, it is known as the tenths place. For example, in the number 1.9, 9 is placed at the tenths value.

Sorry i really need my points

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
