plis yg tau silakan jawab

Aku jawab no 13-15 aja ya :))

13) Pecahan paling sederhana 32/56
= 32/56 (masing² bagi 8)
= 4/7 (a)

14) Urutkan bilangan dari terkecil
6/7 = 6/7 = 6000/7000
0,297 = 297/1000 = 2709/7000
45% = 45/100 = 3150/7000
3/8 = 3/8 = 2625/7000
1 1/10 = 11/10 = 7700/7000
( samain penyebutnya ketemu 7000)
= 0,297 ; 3/8 ; 45% ; 6/7 ; 1 1/10 (c)

15) 5 3/4 + 1 1/3 : 2/3
= 5 3/4 + ( 4/3 x 3/2 )
= 5 3/4 + 2
= 5 3/4 + 1 4/4
= 6 7/4
= 7 3/4 ( B )
