Lemme get a mic pick 2- lemme get a di. ck pick too-

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

35=5×77=7×1when we simplify 7 by 7we will get 5 and 1, 5 divided by 1 is 5
