Answer 1

Answer:

Step-by-step explanation:

Standard form:-

✨• A rational number is said to be in standard form , if its denominator is a positive integer and the numerator and denominator have no common factor other than 1.✓

✨• A rational number is said to be in standard form if the Highest Common Factor or the HCF of numerator and denominator is 1.✓

✨• Always the negative sign in standard form is with the numerator .✓

✨•Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.✓

✨•The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers. When we shift the variable terms to the left side of the equation and everything else to the right side, we get . This equation is now in standard form.✓

✨•A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). ... For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.✓
