Question

find the equivalent forms of the rational numbers having a common denominator in each of the following collection of rational number (i) 2/5,6/13 (ii) 1/7,2/8 ,3/14​

Answer 1

Answer:

Clearly, such a denominator is the LCM of 4, 6 and 12.

We have, 4 = 2 × 2, 6 = 2 × 3 and 12 = 2 × 2 × 3.

Therefore, LCM of 4, 6 and 12 is 2 × 2 × 3 = 12.

Now, 12 ÷ 4 = 3, 12 ÷ 6 = 2 and 12 ÷ 12 = 1.

Answer 2
