kifflom [539]

Answer: B.) 1 and 111 only.

Step-by-step explanation:

75% = 75/100 = 0.75

0.75 falls into the category of rational numbers. Rational numbers comprises of numbers which can be expressed in the form a/b where a and b are integers and B is not 0. Here, both 75 and 100 are integers, thus 75% is a rational number.

Irrational numbers are the opposite of rational numbers thus, 75% is not irrational.

All rational numbers and irrational numbers are REAL numbers, hence, 75% is a real number.

Natural numbers are whole digits starting from 1 e.g ( 1, 2, 3,......). Hence 75% is not a natural number

Whole numbers are natural numbers including 0. (0, 1, 2,.....). Hence, 75% is not a whole number

Integer numbers are comprises of both positive and negative whole numbers. (..., - 1, - 2, 0, 1, 2,...). Hence, 75% is not an integer.

HELP! There is this question on my test:

Papessa [141]

There are several information's already given in the question. Based on those information's, the answer can be easily deduced.
The equation given in the question is
x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 360
Now
Number of people that became
member of the site = (80/100) * 360
= 288 people
From the above deduction, it can concluded that the correct option among all the options that are given in the question is 288.
