1) 1,25 dikali 3,18= 2) 3 2/3 : 2 1/2 = 3) 2 4/5 dikali 2 3/4 : 1 3/8= tolong dong kak pake cara y

1.) 1.25 x 3.18 = 3.975
2.) 3 2/3 : 2 1/2= 11/3 x 5/2= 11/3 x 2/5= 22/15= 1 7/15
3.) 2 4/5 x 2 3/4 = 77/10 : 1 3/8=77/10 x 8/11 = 28/5= 5 3/5

1,25×3,18
=125/100×318/100
=39375/10000
=7875/2000
=1575/400
