Penjelasan dengan langkah-langkah:

  • 1. 7/9 + 14/6

= 7/9 + 14/6

= (7/9 × 2/2) + (14/6 × 3/3)

= 14/18 + 42/18

= (14 + 42)/18

= 56/18

= 28/9

= 3 1/9

  • 2. 5/6 + 7/8

= 5/6 + 7/8

= (5/6 × 4/4) + (7/8 × 3/3)

= 20/24 + 21/24

= (20 + 21)/24

= 41/24

= 1 17/24

  • 3. 12/6 - 3/4

= 12/6 - 3/4

= (12/6 × 2/2) - (3/4 × 3/3)

= 24/12 - 9/12

= (24 - 9)/12

= 15/12

= 5/4

  • 4. 16/5 - 5/25

= 16/5 - 5/25

= (16/5 × 5/5) - (5/25 × 1/1)

= 80/25 - 5/25

= (80 - 5)/25

= 75/25

= 3/1

= 3
