Question

Expre 3.2‌15 (bar in215) in p/q form

Answer 1

Heya !!!

Let x be 3.215

x = 3.215.215215... (i)

Multiplying 1000 both the sides we get

1000 × x = 3.215 × 1000

1000x = 3215.215215... (ii)

Subtracting both the equations we get

1000x - x = 3215.215215... - 3.215215

999x = 3212

$x = \frac{3212}{999}$

Hope this helps ☺
