Penjelasan dengan langkah-langkah:

4= 17/20
Jawaban:
1. 3/4
2. 5/8
3. 1 5/12
4. 17/20
Penjelasan dengan langkah-langkah:
1. 1/4 + 1/2
= (1 × 2)/(4 × 2) + (1 × 4)/(2 × 4)
= 2/8 + 4/8
= 6/8
= (6 ÷ 2)/(8 ÷ 2)
= 3/4
2. 3/8 + 3/12
= (3 × 12)/(8 × 12) + (3 × 8)/(12 × 8)
= 36/96 + 24/96
= 60/96
= (60 ÷ 12)/(96 ÷ 12)
= 5/8
3. 1/2 + 3/4 + 1/6
= (1/2) + (3/4) + 1/6
= 4/8 + 6/8 + 1/6
= 10/8 + 1/6
= 60/48 + 8/48
= 68/ . 17/20
= (68 ÷ 4)/(48 ÷ 4)
= 17/12
= 1 5/12
4. 4/10 + 3/15 + 5/20
= (4/10) + (3/15) + 5/20
= 60/150 + 30/150 + 5/20
= 90/150 + 5/20
= 1800/3000 + 750/3000
= 2550/3000
= (2550 ÷ 150)/(3000 ÷ 150)
= 17/20
