Answer:
a) 0
Step-by-step explanation:
Given that TRAP × 9 = PART and T, R, A, P all have different integer values (that is their values are different). TRAP and PART are both made up of four integers digits, that means 1000 ≤ TRAP and PART ≤ 9999. This means that TRAP × 9 ≤ 10000. The value of R can be gotten from:
[tex]TRAP<\frac{10000}{9}<1112(rounding \ to \ the \ next \ whole \ number)[/tex]
T cannot be 0, therefore T= 1, Since their values are different, R cannot be equal to T, we get that R can only be 0
