What expression represents '' five times the quotient of some number and ten"? A.5(z/10) B.5(z-10) C.5(10/z) D.5(10-z)
maw [93]

Answer:

Option A is correct

5(\frac{z}{10})

Step-by-step explanation:

Let the number be z.

Given the statement:

'' five times the quotient of some number and ten"

" quotient of some number and ten" translated to \frac{z}{10}

"five times the quotient of some number and ten" translated to 5 \times \frac{z}{10}

Then, the expression we get,

5(\frac{z}{10})

Therefore, 5(\frac{z}{10}) expression represents '' five times the quotient of some number and ten"
