nomor 3 - 10 tolong dijawab yaaa plis saya nggak tau

3) 2⅔ × 1 5/6
= 8/3 × 11/6
= 88/18
= 4 16/18
= 4 8/9

4) 3/6 + ⅔
= 3/6 + ( ⅔ × 2/2)
= 3/6 + 4/6
= 7/6
= 1 1/6

5) 4/8 + 5/6
= ( 4/8 × 3/3 ) + ( 5/6 × 4/4)
= 12/24 + 20/24
= 32/24
= 1 8/24
= 1 ⅓

6) 2 2/4 + 3 3/6
= 10/4 + 21/6
= ( 10/4 × 3/3) + ( 21/6 × 2/2)
= 30/12 + 42/12
= 72/12
= 6

7) 3/8 ÷ 4/5
= 3/8 × 5/4
= 15/32

8) 2 ⅔ ÷ 3 ¼
= 8/3 ÷ 13/4
= 8/3 × 4/13
= 32/39

9) 0,25 × ⅔
= 25/100 × ⅔
= 50/300
= 1/6

10) 0,15 × 0,32
= 15/100 × 32/100
= 480/10000
= 0,048
