Question

using ratioal approximations what is an inequality statement comparing square root of 81 and 88 enter greater than or lesser than sign

Answer 1

convert 0.72 into a rational number in its simpleiest form

Answer 2

The rational approximation for the square root of 81 is 9, and for the square root of 88 is approximately 9.38.

So, the inequality statement comparing the two would be: √81 < √88.

Answer 3

To convert a decimal number into a rational number, we can express it as a fraction.

Given the decimal number 0.72, we can write it as 72/100 since there are two decimal places.

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

So, 72/100 simplifies to 9/12.

Further simplifying, we can divide the numerator and denominator by their greatest common divisor, which is 3.

Therefore, 9/12 simplifies to 3/4.

So, 0.72 as a rational number in simplest form is 3/4.
