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
