The two numbers are


To find:
The highest common factor (HCF) of A and B
Solution:
We have,
...(i)

All the factors of A are prime but the factors of B are not prime. So, it can be written as
...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,

Therefore, the highest common factor (HCF) of A and B is 3.

Answer:
5/12 is smaller than 6/8
Step-by-step explanation:
5/12<6/8
Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets
