tolong jawab dengan caranya
7 1/2+5 1/4 =
Jawaban:
1. 7 1/2 + 5 1/4
= 15/2 + 21/4
= 30/4 + 21/4
= 51/4
= 12 ³/4
2. 3 3/9 + 8 2/6
= 30/9 + 50/6
= 120/36 + 300/36
= 420/36
= 11 24/36
= 11 2/3
3. 4 5/9 + 9 2/3
= 41/9 + 29/3
= 41/9 + 87/9
= 128/9
= 14 ²/9
4. 3/8 + 1 2/3 + 6 3/5
= 3/8 + 5/3 + 33/5
= 45/120 + 300/120 + 792/120
= 1137/120
= 9 57/120
= 9 19/40
5. 2 1/4 + 3 2/3 + 4 3/5
= 9/4 + 11/3 + 23/5
= 135/60 + 220/60 + 276/60
= 631/60
= 10 31/60
