5. 2/5+3/10+2/3
6. 4/9×3/4÷2/5
tolong dijawab ya
yang no 3 itu pecahan campuran . terimakasih
1. 1/4+3/5
1. 1/4 + 3/5 = 5/20 + 14/20 = 19/20
2. 5/7 – 7/2 = 10/14 – 49/14 = – 39/14
3. 2 1/3 + 3 1/2 = 7/3 + 7/2
= 14/6 + 21/6 = 35/6
4. 2,5 + 20% – 1/2 = 25/10 + 20/100 – 1/2
= 25/10 + 2/10 – 5/10
= 22/10
5. 2/5 + 3/10 + 2/3 = 12/30 + 9/30 + 20/30
= 41/30
6. 4/9 x 3/4 ÷ 2/5 = 12/36 ÷ 2/5
= 12/36 x 5/2
= 60/72 = 5/6
