they are not making one change to the second no to make
it equilent to the first. i) 6/7,54/63​

Answer 1

Answer:

Step-by-step explanation:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Both 5 and -7 are integers. The definition of a rational numbers is a number of the form p/q where p and q are integers and q is not equal to 0. Both 5 and -7 are integers and -7 is a non-zero integer. Therefore, 5/-7 or -5/7 is a rational number.

Equivalent rational numbers by multiplication: If ab is a rational number and m is a non-zero integer then a×mb×m is a rational number equivalent to ab. For example, rational numbers 1215, 2025, −28−35, −48−60 are equivalent to the rational number 45.

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
