1.5 Determine the base of the numbers in each case for the following operations to be correct.
(a) 14/2=5 (b) 54/4 = 13 (c) 24+17=40
(a) 14/2 = 5
(1*b+4*1)/2*1= 5*1
(b+4)/2=5
b+4=10
b=10-4
b =6
(b) 54/4 =13
(5*b+4*1)/4*1= (1*b+3*1)
(5b+4)/4 = b+3
5b+4=4b+12
5b-4b=12-4
b =8
(c) 24+17 =40
2*b+4*1+1*b+7*1 = 4*b
3b+11=4b
4b-3b = 11
b =11.
