Which of the rational number is greater 3 4 and 0

We have to compare the rational numbers 3 4 and 0 . A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero. As we know that all positive rational numbers are greater than zero. So, 3 4 > 0

Which of the rational number is greater - 1 2 and 4 - 7

We have to compare the rational numbers - 1 2 and 4 - 7 . Method of Comparing Rational Numbers 1 ) Express the rational numbers with positive denominators. So, - 1 2 and - 4 7 2 ) Take L.C.M. of the positive denominators. L C M of 2 and 7 is 14 3 ) Express each rational number with L.C.M. as common denominator. - 1 2 = - 1 × 7 2 × 7 = - 7 14 - 4 7 = - 4 × 2 7 × 2 = - 8 14 4 ) Compare the numerators. The rational number having the greater numerator is greater. On comparing numerators of - 7 14 and - 8 14 , we find that - 7 > - 8 Therefore, - 7 14 > - 8 14 ⇒ - 1 2 > 4 - 7

Which of the rational number is greater 8 15 and 3 10

We have to compare the rational numbers 8 15 and 3 10 Method of Comparing Rational Numbers 1 ) Express the rational numbers with positive denominators. 2 ) Take L.C.M. of the positive denominators. L C M of 15 and 10 is 30 3 ) Express each rational number with L.C.M. as common denominator. 8 15 = 8 × 2 15 × 2 = 16 30 3 10 = 3 × 3 10 × 3 = 9 30 4 ) Compare the numerators. The rational number having the greater numerator is greater. On comparing numerators of 16 30 and 9 30 , we find that 16 > 9 Therefore, 16 30 > 9 30 ⇒ 8 15 > 3 10

Which of the rational number is greater - 1 2 and 8 - 5

We have to compare the rational numbers - 1 2 and 8 - 5 Method of Comparing Rational Numbers 1 ) Express the rational numbers with positive denominators. - 1 2 and - 8 5 2 ) Take L.C.M. of the positive denominators. L C M of 2 and 5 is 10 3 ) Express each rational number with L.C.M. as common denominator. - 1 2 = - 1 × 5 2 × 5 = - 5 10 - 8 5 = - 8 × 2 5 × 2 = - 16 10 4 ) Compare the numerators. The rational number having the greater numerator is greater. On comparing numerators of - 5 10 and - 16 10 , we find that - 5 > - 16 Therefore, - 5 10 > - 16 10 ⇒ - 1 2 > 8 - 5
