Math problem: The sum of dividend, divisor, quotient and remainder is 77, the known quotient is 9 and the remainder is 4. What is the divisor?
Solution: Because dividend = divisor x quotient+remainder =9 divisor +4.
Dividend+Divider+Quotient+Remainder =77
So 9 divisor +4+ divisor +9+4=77.
10 divisor =60
Frequency divider =6.
