How do you translate word phrases to algebraic expressions: the quotient of seven, and 1 less than a number?
Let the quotient be
Let some number be
Quotient is the answer obtained from a division. Unless it is specified otherwise the second condition is what you are dividing by (divisor).
For example: 3 divide by 4.
So for your question I am taking '1 less than a number' to be the divisor.
