How do you do the problems step by step only the even ones and i will give brainliest to whoever gives the answers (in 44 there are 30 zeroes

If its a negative exponent it would be
.000050

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

1.3 and 1 1/3 are both closest to 1. hope this ; )
