dinda mempunyai pita 7 1/2m dan membeli lagi di toko 3 1/3 m. pita tersebut digunakan 4 3/4m dan digunakan lagi 4 1/6m

7½+3⅓ - ( 4¾ +4 1/6)
= 15/2 + 10/3 - (19/4 + 25/6)
= 45/6+20/6 - (57/12+50/12)
= 65/6 - 107/12
=130/12 - 107/12
= 1 11/12

Pembelian pita :

<=> 7 1/2 + 3 1/3
<=> 15/2 + 10/3
<=> 45/6 + 20/6
<=> 65/6
<=> 10 5/6 m

Digunakan :
<=> 4 3/4 + 4 1/6
<=> 17/4 + 25/6
<=> 102/24 + 100/24
<=> 8 10/24

Sisa pita :
<=> 10 5/6 - 8 10/24
<=> 65/6 - 202/24
<=> 260/24 - 202/24
<=> 58/24
<=> 29/12
<=> 2 5/24 m ---> 2,46 m

semoga membantu :)
