1. 2/1 × 1/10 ÷ 6/3 2 3/7 + 1 1/4 - 0,5 Tolong ya

1) 2/1 x 1/10 : 6/3
    = 1/5 x 3/6
    = 3/30
    = 1/10

2) 3/7 + 1 1/4 - 0,5
    = 3/7 + 5/4 - 1/2
    = 12/28 + 35/28 - 14/28
    = 47/28 - 14/28
    = 33/28
    = 1 5/28

1. 2/1 × 1/10 ÷ 6/3 = 2/1 × 1/10 × 3/6 = 6/60 = 1/10
2. 3/7 + 1 1/4 - 0,5 = 3/7 + 5/4 - (5/10 = 1/2)
= 12/28 + 35/28 - 14/28 = 47/28 - 14/28 = 33/28
= 1 5/28
maaf kalo salah
