Write three equivalent rational numbers of - 7 12 .

Given, The rational number is - 7 12 . We need to write three equivalent rational numbers of the given rational number. Equivalent rational numbers are rational numbers that have same value but which are represented in different form. Ex: If p q and r s are two equivalent rational numbers, then p × m q × m = r s or p ÷ m q ÷ m = r s ( m ≠ 0 ) . Therefore, three equivalent rational numbers are: - 7 × 2 12 × 2 = - 14 24 - 7 × 3 12 × 3 = - 21 36 - 7 × 4 12 × 4 = - 28 48 Hence, three equivalent rational numbers are - 14 24 , - 21 36 and - 28 48 .

Write three equivalent rational numbers of 6 7

Given, 6 7 Equivalent rational numbers are rational numbers that have the same value but which are represented in a different form. In order to find equivalent rational numbers, we need to multiply the numerator and denominator of the given number with the same number. Therefore, 6 7 × 2 2 = 12 14 , 6 7 × 3 3 = 18 21 and 6 7 × 4 4 = 24 28 Hence, three rational numbers equivalent to 6 7 are 12 14 , 18 21 , 24 28 .

Write three equivalent rational numbers of 15 19

Given, 15 19 Equivalent rational numbers are rational numbers that have the same value but which are represented in a different form. In order to find equivalent rational numbers, we need to multiply the numerator and denominator of the given number with the same number. Therefore, 15 19 × 2 2 = 30 38 , 15 19 × 3 3 = 24 57 and 15 19 × 4 4 = 60 76 Hence, three rational numbers equivalent to 6 7 are 12 14 , 18 21 , 24 28 .
