Step-by-step explanation:

Question: Write 23/69 in standard form.

Solution: Given, 23/69

If we take out the H.C.F. of 23 and 69, we get;

23 = 1 x 23

69 = 1 x 3 x 23

As we can see here, there is one more factor common between 23 and 69 other than 1, which is 23 itself, therefore if we cancel the common factor from numerator and denominator, we get;

23/69 = 1/3

Question: Which of the following rational numbers is equivalent to 2/3?

(a) 3/2

(b) 4/9

(c) 4/6

(d) 9/4

Solution: The answer is (c).

4 = 2 x 2

6 = 2 x 3

Since 2 is the common factor here, then we will cancel it from numerator and denominator.

Therefore, 4/6 = 2/3
