Write a division expression with quotient that is greater than 8 divided 0.001
Jet001 [13]

Answer:

Expression is '98 divided by 0.005' i.e. \frac{98}{0.005}.

Step-by-step explanation:

We have that,

The quotient of 8 divided by 0.001 is given by,

\frac{8}{0.001} = \frac{8\times 1000}{1} = 8000.

It is required to find a division expression having quotient greater than 8000.

Let us consider,

'98 divided by 0.005'

i.e. \frac{98}{0.005}

i.e. \frac{98\times 1000}{5}

i.e. 98 × 200

i.e. 19,600

Thus, the get the quotient of the new expression 19,600 > 8000.

Hence, the required expression is '98 divided by 0.005' i.e. \frac{98}{0.005}.
