Which of the following numbers can be classified as a whole number, natural number, integer, and rational number? 0.4. -78 15 0

0.4  since the number is non terminating and non repeating therefore it is irrational number.

-78  A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero

15  The number 15 is a rational number. It is an integer and all integers are rational numbers.

0 Yes zero is a rational number. Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
