Question

Express 6.23 bar as a rational number and bar is upon 3 only

Answer 1

Answer:

561/90

Step-by-step explanation:

๑ For the easiest solution, we will make few equations.

We already have an equation i.e

x = 6.23333.. ( bar on 3 ) __[Eq. i]

Let's multiply it by 10 :

10x = 62.333.. ___[equation ii]

Again, we'll multiply the eq.i. but this time by 100 for the next equation.

100x = 623.333..

～Now,we can see that eq. iii and eq. i can be subtracted. So,

(eq. iii) - (eq. ii)

623.333-62.33 =100x - 10x

= 561 = 90x

= 561/90 = x
