Is 4.32 as a mixed number 4 32/100?

Yes, but you might want to simplify the fraction to 4 8/25

Your answer would be letter D because the mixed number you chose is correct but it is not in simplest form so 4 32/100= 4 4/25. I hope i have 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
