.17 because there is a zero behind the 7! .170 and .165. .17 is bigger
8.57 for the first one and, I’m not sure a bout the second time though

Length of the room is 5 m and width is 5 + 2 = 7 m.

Answer:
It is mainly used while doing scientific notation. If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100.A quarter is 0.25 dollars so the ratio between 1 dollar and a quarter is 1/0.25(it means the dollar and the quarter which is 0.25 dollars) and that equals =4
You did the top right but the denominator is 0 so the slope in undefined or 0.
Hope this helps!
