Sue's teahcer asked her to finnd 42.6 divided by 10 to the power of 2. how should sue move the decimal point to get the correct qoutient?

By every digits that are zero divided, you move the decimal to the left. So if it's 10, there's only one zero. So you move it one time to the left.

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
