4.16/5-5/25
Tolong di jawab ya kak
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
[tex] [/tex]
- 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
[tex] [/tex]
- 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
