1 answer:
The first two numbers are rational, because they are rational numbers with a finite number of decimal digits.
The third number is also rational, because , which is integer, and thus rational as well.
We can't say that the fourth number is rational, because we don't know how the number continues. A decimal number is rational if its decimal digits are finitely many, or if they show some periodicity. This doesn't seem the case, so the number may be irrational.
The last number is rational, because it is a periodic decimal number, and as such it admits a fraction that generates it.

Answer:
Step-by-step explanation:
Comparing the triangles in the given questions, the following can be deduced:
5. The scale factor = =
≠
So that;
QR is similar to UT, PR is similar to US, but PQ is NOT similar to TS.
Thus, the triangles are NOT similar.
6. Scale factor = =
=
= 1.5
So that;
QR is similar to UT, PR is similar to US, but PQ is similar to TS.
Thus, the triangles are similar by Side-Side-Side (SSS).
7. Here, an exact scale factor can not be determined. Thus, the triangles are NOT similar.
