Tolong di jawab ya kak plissssssss

Penjelasan dengan langkah-langkah:

1. 6+2 3/4 - 1/4

= 6/1 + 11/4 - 1/4

= 24/4 + 11/4 - 1/4

= 34/11

= 3 1/11

2. 3 - (7/2 - 1 1/5)

= 3/1 - (7/2 - 6/5)

= 3/1 - (35/10 - 12/10)

= 3/1 - 23/10

= 30/10 - 23/10

= 7/10

3. 3 × (1 ½ + ⅔)

= 3 × (3/2 + 2/3)

= 3 × (9/6 + 4/6)

= 3 × 13/6

= 39/6

= 13/2

= 6 ½

4. ⅞ + (2 ÷ 1 ⅓) × 3

= 7/8 + (2/1 ÷ 4/3) × 3

= 7/8 + (2/1 × 3/4) × 3

= 7/8 + 6/4 × 3

= 7/8 + (6/4 × 3)

= 7/8 + 18/4

= 7/8 + 36/8

= 43/8

= 5 ⅜

5. 5,5 - 2/5 × 2 + 1 ¾

= 55/10 - 2/5 × 2 + 7/4

= 55/10 - (2/5 × 2) + 7/4

= 55/10 - 4/5 + 7/4

= 110/20 - 16/20 + 35/20

= 129/20

= 6 9/20
