b) 16/15 : 32:25 = 16/15 * 25/32 = 5/6
c) 48/49 : 40/21 = 48/49 * 21/40 = 6*3 / 7*5 = 18/35
d) 81/50 : 54/25 = 81/50 * 25/54 = 3 / 2 * 2 = 3/4
Explicație pas cu pas:
a)6/5÷7/8=6/5*8/7=48/35
b)16/15÷32/25=16/15*25/32=1/15*25/2=25/30=5/6
c)48/49÷40/21=48/49*21/40=1008/1960=126/245
d)81/50÷54/25=81/50*25/54=81/2*1/54=81/108=9/12=3/4
