Answer:
The compatible numbers are 630 and 14. The quotient is about 92. The quotient is [tex]92\frac{4}{7}[/tex].
Step-by-step explanation:
The dividend is 648 and the divisor is 7.
The number 630 is a compatible number because product of 7 and 9 is 63.
So, 648 can be written as
[tex]648=630+18[/tex]
The number 14 is a compatible number because product of 7 and 2 is 14. So, 648 can be written as
[tex]648=630+14+4[/tex]
[tex]\frac{648}{7}=\frac{630+14+4}{7}=90+2+\frac{4}{7}=92+\frac{4}{7}[/tex]
Therefore the compatible numbers are 630 and 14. The quotient is [tex]92\frac{4}{7}[/tex].
