To find an equivalent fraction we multiply or divide both numerator and denominator by the same number.

For the first number.

`11/22`

We notice that 11 and 22 are both multipliers of 11, so we divide both by 11.

`==> 11/22 = (11-: 11)/(22-:11) = 1/2`

Then, the equivalent fraction is `1/2` .

`5/8`

To find an equivalent fraction we multiply both numerator and denominator by any integer.

==> `5/8 = (5*2)/(8*2) = 10/16`

OR: `5/8 = (5*4)/(8*4)= 20/32 1/5 `

`==gt 1/5 = (1*3)/(5*3)= 3/15 12/30 `

`==gt 12/30= (12-:6)/(30-: 6)= 2/5`
