1. 5+2/3= 2. 2/5-4= 3. 0,5×1/3= 4. 10:0,3= Plisss bantu butuh banget

Mapel : Matematika
Kelas : IV SD
Bab : Bilangan Bulat

Pembahasan :
5 + 2/3
= 15/3 + 2/3
= (15 + 2)/3
= 17/3

2/5 - 4
= 2/5 - 20/5
= (2 - 20)/5
= -18/5

0,5 x 1/3
= 5/10 x 1/3
= 1/2 x 1/3
= 1/6

10 : 0,3
= 10 : 3/10
= 10 x 10/3
= 100/3

1. 5+2/3 = 5 2/3
2. 2/5-4 = -3 3/5
3. 0,5x1/3= 1/6
4. 10:0,3 = 100/3= 33 1/3

semoga bermanfaat, trimakasih.
