This is my solution! I started by finding out what E was. I realised that it had to end in one. So I wrote out my 3x table. The only one ending in a one was 21. So E had to be 7. I then used this to work out the rest.
a=4
b=2
c=8
d=5
e=7
for the second problem I worked it out in the same way. I wrote out the 3x table to work out that the only multiple ending in in 2 was 12. So j had to be four. I used this method to work out the rest of the numbers.
f=8
g=5
h=7
i=1
j=4 By Clare
