3.which one of these is a rational number
a 150
b. 441
c. 200
d. 250##
The first three are rational numbers.
For the last one, no idea what the ## in 250## stands for
@Reiny that is her answer
To determine which one of these numbers is a rational number, we need to understand what a rational number is. A rational number is any number that can be expressed as a ratio of two integers, where the denominator is not zero.
Let's check each option to see if it meets the criteria:
a) 150: Since 150 can be expressed as the ratio 150/1, it is a rational number.
b) 441: Similarly, 441 can be expressed as the ratio 441/1, so it is also a rational number.
c) 200: We can express 200 as the ratio 200/1, which means it is a rational number.
d) 250: Like the previous options, 250 can be expressed as the ratio 250/1, making it a rational number as well.
Therefore, all of the given options (a, b, c, and d) are rational numbers because they can be written as a ratio of two integers.
To identify which one of these numbers is a rational number, we need to understand what a rational number is. A rational number is any number that can be expressed as a fraction, where both the numerator and the denominator are integers.
Option a: 150
To determine if 150 is a rational number, we can express it as a fraction: 150/1. Since both the numerator and the denominator (150 and 1) are integers, 150 is indeed a rational number.
Option b: 441
Similarly, we can express 441 as a fraction: 441/1. Both the numerator and the denominator are integers, so 441 is also a rational number.
Option c: 200
Again, we can express 200 as a fraction: 200/1. Just like the previous options, both the numerator and the denominator are integers, so 200 is a rational number.
Option d: 250
Once more, we can express 250 as a fraction: 250/1. As with the other options, both the numerator and the denominator are integers, so 250 is a rational number.
In conclusion, all of the given options (150, 441, 200, and 250) are rational numbers since they can be expressed as fractions with integer numerators and denominators.
