A mistake was made in the steps shown to simplify the expression. Which ste 1 + 32

1

+

9

5° +|-10 = 2

Step 1: = 7+3 + 10 = 2

Step 2: = - + 10 = 2

Step 3: = + 10 = 2

Step 4: = 2 + 10 = 2

Step 5: = 12 = 2

Step 6: = 6

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
