Negative integers, rationals and real numbers
To any set that contains it! It belongs to {sqrt(30)}, or {45, sqrt(30), pi, -3/7}, or irrational numbers, or real numbers between -6 and 6, or all real numbers or complex numbers, etc.
30 belongs to the set of natural numbers
To any set that contains it! It belongs to {30}, or {45, sqrt(2), 30, pi, -3/7}, or all whole numbers between 23 and 53, or multiples of 5, or square roots of 900, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
30 is not a ratio. In a ratio, two numbers are always specified, for example, 30:1. If that's what you mean, you can simply multiply both numbers - in this case, 30 and 1 - by any real number (both by the same real number), to get an equivalent ratio.

Real numbers, Rational numbers, and Integers.The other three are Irrational (numbers that cannot be expressed as fractions), Whole numbers (0,1,2,3,4...) and Natural numbers (1,2,3,4,5...).EDIT: There is also imaginary numbers (√-1, often expressed as i ) and complex numbers (numbers that contain both a real and imaginary part i.e. a+bi where a and b are real numbers and i is an imaginary number)
A mouse is a mammal that belongs to the rodent family. Mice fall under the Muridae family and the Mus genus. There are over 30 known species of mice in the world.

Money 30 + 70 = 100 30p + 70p = 100p or £1
basically the answer is 5, 17, 23. there is no real explanation to this answer.
a+b=-7 rearrange: b= -a-7=-(a+7) substitute into: ab=30 -a(a+7)=30 -a^2-7a-30=0 a^2+7a+30=0 x = complex number, therefore there are no two Real numbers that exist that satisfy these two conditions.
