Write five more rational numbers in the following pattern 14 - 9 , 28 - 18 , 42 - 27 , . . . .

Two rational numbers are said to be equivalent if the product of the numerator of the first and the denominator of the second rational number is equal to the product of the numerator of the second and the denominator of the first rational number. ⇒ If p q = r s ⇒ p × s = r × q An equivalent rational number is obtained by either multiplying or dividing the numerator and denominator of the rational number by the same number. Given pattern is 14 - 9 , 28 - 18 , 42 - 27 , . . . . 14 - 9 = 14 × 2 - 9 × 2 = 28 - 18 ; 14 - 9 = 14 × 3 - 9 × 3 = 42 - 27 ; 14 - 9 = 14 × 4 - 9 × 4 = 56 - 36 ; 14 - 9 = 14 × 5 - 9 × 5 = 70 - 45 14 - 9 = 14 × 6 - 9 × 6 = 84 - 54 ; 14 - 9 = 14 × 7 - 9 × 7 = 98 - 63 and 14 - 9 = 14 × 8 - 9 × 8 = 112 - 72 Hence, five more rational numbers in the pattern 14 - 9 , 28 - 18 , 42 - 27 , . . . . are 56 - 36 , 70 - 45 , 84 - 54 , 98 - 63 , 112 - 72

Write five more rational numbers in the following pattern - 11 15 , 22 - 30 , - 33 45 , . . . .

Two rational numbers are said to be equivalent if the product of the numerator of the first and the denominator of the second rational number is equal to the product of the numerator of the second and the denominator of the first rational number. ⇒ If p q = r s ⇒ p × s = r × q An equivalent rational number is obtained by either multiplying or dividing the numerator and denominator of the rational number by the same number. Given pattern is - 11 15 , 22 - 30 , - 33 45 , . . . . - 11 15 = - 11 × - 2 15 × - 2 = 22 - 30 ; - 11 15 = - 11 × 3 15 × 3 = - 33 45 ; - 11 15 = - 11 × - 4 15 × - 4 = 44 - 60 ; - 11 15 = - 11 × 5 15 × 5 = - 55 75 - 11 15 = - 11 × - 6 15 × - 6 = 66 - 90 ; - 11 15 = - 11 × 7 15 × 7 = - 77 105 and - 11 15 = - 11 × - 8 15 × - 8 = 88 - 120 Hence, five more rational numbers in the pattern - 11 15 , 22 - 30 , - 33 45 , . . . . are 44 - 60 , - 55 75 , 66 - 90 , - 77 105 , 88 - 120

Write five more rational numbers in the following pattern 15 8 , - 30 16 , 45 24 , . . . .

Two rational numbers are said to be equivalent if the product of the numerator of the first and the denominator of the second rational number is equal to the product of the numerator of the second and the denominator of the first rational number. ⇒ If p q = r s ⇒ p × s = r × q An equivalent rational number is obtained by either multiplying or dividing the numerator and denominator of the rational number by the same number. Given pattern is 15 8 , - 30 16 , 45 24 , . . . . 15 8 = 15 × - 2 8 × - 2 = - 30 - 16 ; 15 8 = 15 × 3 8 × 3 = 45 24 ; 15 8 = 15 × - 4 8 × - 4 = - 60 - 32 ; 15 8 = 15 × 5 8 × 5 = 75 40 15 8 = 15 × - 6 8 × - 6 = - 90 - 48 ; 15 8 = 15 × 7 8 × 7 = 105 56 and 15 8 = 15 × - 8 8 × - 8 = - 120 - 64 Hence, five more rational numbers in the pattern 15 8 , - 30 16 , 45 24 , . . . . are - 60 - 32 , 75 40 , - 90 - 48 , 105 56 , - 120 - 64 .
