they asking me to find the answer by using compatible numbers 9÷ 5,138 9 and ? are compatible. the estimate is?

SOLUTION
Now, 9 and 51 are not compatible because 51 cannot divide 9 without a remaider.
The compatible number with 9 that is close to 51 is 54.
Hence,
9 and 54 are compatible.
This will give us
[tex]\frac{5400}{9}=600[/tex]Hence,
The estimate is 600
