Find four rational numbers equivalent to 7 - 15 .

Given, 7 - 15 The two rational numbers are said to equivalent, if one can be obtained from the other by multiplying or dividing its numerator and denominator by the same non-zero number. So, let us multiply the numerator and the denominator of the given rational number by non-zero numbers, 2 , 3 , 4 , 5 , we get, 7 - 15 = 7 × 2 - 15 × 2 = 7 × 3 - 15 × 3 = 7 × 4 - 15 × 4 = 7 × 5 - 15 × 5 ⇒ 7 - 15 = 14 - 30 = 21 - 45 = 28 - 60 = 35 - 75 Hence, the required equivalent rational numbers are 14 − 30 = 21 − 45 = 28 - 60 = 35 − 75 .
