Verified Answer :

(g/3)-10
That is the mathematical expression.
Hope this helps.

Answer:

Given that: 10 less than the quotient of g and 3.

"The quotient of" is a, / (division) operation.

" the quotient of g and 3" is translated to  \(\frac{g}{3}\)

so, " a Less than b " translated to b - a

Then;

"10 less than the quotient of g and 3" means \(\frac{g}{3} -10\)

Therefore, the algebraic expression of 10 less than the quotient of g and 3 is,  \(\frac{g}{3} -10\)
