Question

Which number is divisible by 3?
a.1,438
b.275
c.3,842
d.7,221

Answer 1

add all the numbers together if the total is dividable by 3 u can devide the whole number by 3 ! for example 1438=1+4+3+8=16 and since 16 is not dividable by 3 then 1438 is not either

Answer 2

so the answer is D because the total is 12 ! remember this rule only works for 3

Answer 3
