Soal tantangan! 1. 3 1/4 + 4 5/6 - 3 1/2 2. 5/4 jadikan pecahan desimal! 3. 5/4 - 1/6 - 1/10 Maaf terlalu gampang,jangan protes and pakai cara ya

1. 3 ¼ + 4 5/6 - 3 ½ = 13/4 + 29/6 - 7/2 =
jadikan dulu per 12 karna KPK nya 12
39/12 + 58/12 - 42/12 = 55/12 = 3 5/12

2. 5/4 × 25 = 125/100 = 1,25

3. 5/4 - 1/6 - 1/10 = 75/60 - 10/60 - 6/60 = 54/60 atau 9/10

maaf yah kalo jawabannya nggak sesuai

1. 3 1/4 + 4 5/6 - 3 1/2 = 13/4 + 29/6 - 7/2
= 39/12 + 58/12 - 42/12
= 139/12
= 11 7/12

2. 5/4 = 1,25

3. 5/4 - 1/6 - 1/10 = 75/60 - 10/60 - 6/60
= 59/60
