Answer 6

The rational numbers are numbers that can be written as a fraction of two integers.

Out of the given options, 60 is an integer and can be written as a fraction 60/1, so it is a rational number.

So, the answer is 60.

Answer 7

The irrational numbers are numbers that cannot be written as a fraction of two integers.

Out of the given options, 2√3 is irrational because it involves the square root (√) of a non-perfect square.

So, the answer is 2√3.

Answer 8

I apologize for the error in my previous response.

Upon reviewing the options again, the correct answer is 0.343434..., which is a recurring decimal. Recurring decimals cannot be expressed as a fraction, therefore it is an irrational number.

So, the answer is 0.343434...

Answer 9

To determine which of the following is an irrational number, we need to identify the options that cannot be written as a fraction or a terminating decimal.

Based on the options provided:

-1529 is an integer and can be written as the fraction -1529/1, so it is a rational number.

0.343434... is a repeating decimal and cannot be expressed as a fraction or a terminating decimal, so it is an irrational number.

2√3 involves the square root (√) of a non-perfect square (3), so it is also an irrational number.

87.9821 is a terminating decimal and can be expressed as a fraction (879821/10000), so it is a rational number.

So, the options that are irrational numbers are 0.343434... and 2√3.
