Me on these math questions, . if someone could answer the top two then that would be great.

What questions because i dont see it did u upload it some were on here.

The first one is not similar but the second one is
For the second on if you flip the smaller trapezoid (vertically and horizontally)then the corresponding angles are decreased by a factor of 3
15/3=5
24/3=8 and so on
The first one does not have a pattern like this so that is why they are not similar

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
