WebStep 1: Find the LCM of two rational numbers first. Step 2: Multiply and divide the two rational numbers, by the value that results in the denominators equal to the obtained LCM. Step 3: Once the denominators become the same, follow the same rules as we have discussed for the rational numbers with the same denominators. WebThe product of two rational numbers is -8/9. If one of the numbers is -4/15, find the other. Solution: We know that the product of two rational numbers = -8/9 One of the number = -4/15 ∴ other number is obtained by dividing the product by the given number. Other number = (-8/9)/ (-4/15) = (-8/9) × (15/-4) = (-2/3) × (5/-1) = (-2×5) / (3×-1)
WebThe correct option is A. 17 36. A fraction is terminating only when the prime factors of denominator contains only 2 and 5. Otherwise, the fraction is non-terminating and repeating. For e.g. The prime factors of 250, 25 and 32 in option A, B and C respectively contain only 2 and 5. 250 =2×53, thus 3 250= 0.012 (terminating decimal) WebIrrational numbers are real numbers that cannot be represented as simple fractions. An irrational number cannot be expressed as a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.I rrational numbers are usually expressed as R\Q, where the backward slash symbol denotes ‘set minus’. It can also be expressed as …
