convert 0.72 to a rational number in simplest form

To convert 0.72 to a rational number in simplest form, we need to express it as a fraction. We can do this by noticing that 0.72 is equivalent to 72/100.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 8.

Dividing both 72 and 100 by 8, we get:

72 ÷ 8 = 9
100 ÷ 8 = 12

Therefore, 0.72, when expressed as a rational number in simplest form, is 9/12.

Express 8/11 as a repeating decimal. Mark the cycle of repeating digits with a bar.

To express 8/11 as a repeating decimal, we divide 8 by 11.

When we do this, we get:
0.727272...

The cycle of repeating digits in this case is "72". Therefore, we can express 8/11 as a repeating decimal as 0.72 with a bar over the "72".

Describe the relationship between rational numbers and whole numbers. Are all rational numbers also whole numbers? Are all whole numbers also rational numbers? Give examples to support your answer.

Rational numbers and whole numbers are related, but they are not the same.

All whole numbers are rational numbers. This is because every whole number can be expressed as a fraction with a denominator of 1. For example, the whole number 3 can be written as the rational number 3/1.

However, not all rational numbers are whole numbers. Rational numbers include all numbers that can be expressed as a fraction, where the numerator and denominator are integers and the denominator is not zero. This includes fractions, decimals, and mixed numbers.

For example, the rational number 4/5 is not a whole number because it is a proper fraction and its numerator is smaller than its denominator. The rational number 2.25 is also not a whole number because it is a decimal.

In summary, while all whole numbers are rational numbers, not all rational numbers are whole numbers.
