15712121212/10000000000

Answer 2

Answer:

(1)

$- 25.6875 = \frac{ - 256875}{1000}$

$0.621621621 ..... = \frac{621 - 0}{999} = \frac{621}{999} = \frac{69}{111}$

$15.712121212.... = \frac{15712 - 15}{990} = \frac{15697}{990}$

(2)

0.523

(3)

(b)

$\sqrt{3} \times \sqrt{2} = \sqrt{6}$

(c)

$\sqrt{3} - \sqrt{2} = 0.31783.....$
