recall that a/b to decimal is just a ÷ b, so 2/9 is just 2 ÷ 9.
check the picture below.
0.1 / 100 * 10 = 0.01 pounds
Using the sum (addition) and two 2-digit addends, 12 + 34 can be answered without regrouping.
Answer:
Your number is (3 sqrt(2)) / sqrt(2) = 3, and is a rational number indeed. I don't know exactly how to interpret the rest of the question. If r is a positive rational number and p is some positive real number, then sqrt(r^2 p) / sqrt(p) is always rational, being equal r. Possibly your question refers to situtions in which sqrt(c) is not uniquely determined, as for c negative real number or complex non-real number. In those situations a discussion is necessary. Also, in general expressions the discussion is necesary, because the denominator must be different from 0, and so on.
