1. 3 1/2 × 1 1/7 + 6,5 = 2. 4 1/5 × 3 1/8 = 3. 5 3/4 - 2 1/5 + 0,3 = 4. 4 1/5 × 1 1/3 + 1,59 : 0,3 = 5 4,6 - 1/25 + 2,125 = plis jawab pake cara ya

1. 3 1/2 × 11/7 + 6.5
= 7/2 × 11/7 + 13/2
= 77/14 + 13/2
= 77/14 + 91/14
= 168/14
= 12

2. 4 1/5 × 3 1/8
= 21/5 × 25/8
= 525/40
= 105/8

3.

ini caranya no 3

5 3/4 - 2 1/5 + 0,
=(5 - 2) + (3/4 - 1/5)
=3 + (15/20 - 4/20)
=3 + 11/20
=3 11/20 + 0,3
=3 + (11/20 + 3/10)
=3 + (11/20 + 6/20)
=3 + 17/20
=3 17/20

Maaf ya kalau salah
