1. (3 1/5×1 2/5):3 1/2 2. 2 1/4×(5 1/3:2) 3. 3 1/3:(1 1/3×1 2/4) 4. 7 1/2:3 1/6 tolong jawab yah pake cara soalnya wat besok

Nomor 1
= (16/5 × 7/5) : 7/2
= 112/25 × 2/7
= 224/175
= 32/25

Nomor 2
= 9/4 × (16/3 : 2/1)
= 9/4 × (16/3 × 1/2)
= 9/4 × 16/6
= 144/24
= 6

Nomor 3
= 10/3 : (10/3 × 6/4)
= 10/3 : 60/12
= 10/3 × 12/60
= 120/180
= 2/3

Nomor 4
= 15/2 : 19/6
= 15/2 × 6/19
= 90/38
= 45/19
