You can compare them mentally! A fraction ia divided into 2 parts, however a decimal is not! Also the strategies you have to use are different. When finding the product/sum/quotient of a fraction you need to find a common denominator. But, with a decimal all you need to do is place the decimals correctly!

(Z-6) divided by 3 for z= 15.9

scoray [572]

Simply plug in $\sf{z=15.9}$ into $\sf{\frac{z-6}{3}}$

So:

$\sf{\frac{15.9-6}{3}}$

Simplify that more:

$\sf{\frac{9.9}{3}}$

And that finally becomes

$\sf{3.3}$

So when $\sf{z=15.9}$ the answer will be $\boxed{\sf{3.3}}$
