Bab Bilangan Pecahan
Matematika SD Kelas V

1] 10 3/7 - 4 2/3
= 73/7 - 14/3
= (73 x 3 - 14 x 7)/(7 x 3)
= (219 - 98)/21
= 121/21
= 5 16/21

2] 15 1/10 - 9 2/5
= 151/10 - 47/5
= 151/10 - 94/10
= 57/10
= 5 7/10

3] 1 1/3 + 2 3/5 - 4/8
= 4/3 + 13/5 - 1/2
= 40/30 + 78/30 - 15/30
= 103/30
= 3 13/30

1) 10 3/7 - 4 2/3=

10×7+2/7 - 4×3+2/3=
70+2/7 - 12+2/3=
72/7 - 14/3=
jadi dari bilangan 10 3/7 - 4 2/3 = 118/21
bentuk alternatihnya = 5 13/21

udah cuman itu aja yang saya jawab
