Solve the following equation and express the root in p q form(where q ≠ 0 and p , q are two integers. 7 x = 14

Given, 7 x = 14 ⇒ x = 14 7 ⇒ x = 2 Now, 2 can be expressed in p q form by dividing it by 1 . Therefore, 2 1 is the p q form the root of the equation.

Solve the following equation and express the roots in p q form(where q ≠ 0 and p , q are two integers. 4 p + 32 = 0

Given, 4 p + 32 = 0 ⇒ 4 p = - 32 ⇒ p = - 32 4 ⇒ p = - 8 Now, - 8 can be expressed in p q form by dividing it by 1 . Therefore, - 8 1 is the p q form the root of the equation.

Solve the following equation and express the root in form p q (Where q ≠ 0 and p , q are two integers): 2 x + _ _ _ _ _ = _ _ _ _ _ (Put the rational number yourself)

Given, the equation: 2 x + _ _ _ _ _ = _ _ _ _ _ Let assume, the equation is 2 x + 3 7 = 15 21 Now, 2 x + 3 7 = 15 21 ⇒ 2 x = 15 21 - 3 7 ⇒ 2 x = 15 - 9 21 ⇒ 2 x = 6 21 ⇒ x = 6 21 × 2 ⇒ x = 1 7 Now, 1 7 is a rational number where 1 , 7 both are integers. So, for an equation: 2 x + 3 7 = 15 21 , the root is 1 7 . It is in p q from, where p , q are two integers and q ≠ 0 .

Find rational numbers between - 3 5 and 1 2 .

Rational numbers are numbers that can be represented in p q form, where p , q are two integers and q ≠ 0 . There are infinite rational numbers between any two rational numbers. To find rational numbers between two rational numbers, we have to make the denominator same. Now, - 3 5 = - 6 10 and 1 2 = 5 10 So, rational numbers between - 3 5 and 1 2 are - 5 10 , - 3 10 , 2 10 , 3 10 .
