Which number is a rational terminating decimal?
A: 1/3
B: 3.46410161514
C: 6.2449979984
D: 5/11
E: 7/8
A rational number is one that can be written as a fraction, where the numerator and denominator are both integers. A terminating decimal is a decimal number that ends after a finite number of digits.
Looking at the options, we can see that A: 1/3 and D: 5/11 are fractions, and they can be written as terminating decimals.
To determine which fraction is a terminating decimal, we can convert them to decimals.
For A: 1/3,
1 ÷ 3 = 0.33333333...
The decimal representation of 1/3 is a repeating decimal, not a terminating decimal.
For D: 5/11,
5 ÷ 11 = 0.45454545...
The decimal representation of 5/11 is a repeating decimal, not a terminating decimal.
Therefore, none of the given options are rational terminating decimals. The correct answer is none of the above (NOTA).
that is not one of the options, try and redo the equation again because it cant be none of the above
Apologies for the confusion. Let's re-evaluate the given options:
A: 1/3 can be expressed as a decimal by dividing 1 by 3: 1 ÷ 3 = 0.33333333...
This is a repeating decimal and not a terminating decimal.
B: 3.46410161514 is already a decimal and is not a fraction. It is not a rational number.
C: 6.2449979984 is already a decimal and is not a fraction. It is not a rational number.
D: 5/11 can be expressed as a decimal by dividing 5 by 11: 5 ÷ 11 = 0.45454545...
This is a repeating decimal and not a terminating decimal.
E: 7/8 can be expressed as a decimal by dividing 7 by 8: 7 ÷ 8 = 0.875
This is a terminating decimal.
Therefore, the rational terminating decimal is E: 7/8.
