Answer 2

a) 6:0,2=6/1:2/10=60/10•10/2=30
b) 2:0,05=2/1:5/100=200/100•100/5=40
c) 15:0,03=15/1:3/100=1500/100•100/3=500
d) 7:0,07=7/1:7/100=700/100•100/7=100
e) 42:0,7=42/1:7/10=420/10•10/7=20
f) 42:0,07=42/1:7/100=4200/100•100/7=200
g) 42:0,007=42/1:7/1000=42000/1000•1000/7=2000
h) 10:0,4=10/1:4/10=100/10•10/4=25
i) 225:1,5=225/1:15/10=2250/10•10/15=150
j) 5:0,25=5/1:25/100=500/100•100/25=20
k) 1,44:1,2=144/100:12/10=144/100•100/120= 144/120=36/30=12/10=1,2
l) 14,4:1,2=144/12=12
