$p\%=\dfrac{p}{100}\\\\175\%=\dfrac{175}{100}=\dfrac{175:25}{100:25}=\dfrac{7}{4}$

Round 6.7086 to the nearest thousandth

Bingel [31]

$\text {Hello! Let's solve this Problem!}$

$\text {To round to the nearest thousandth you must underline the thousandth place}$ $\text {(which is 8), point an arrow to 6 (in the ten-thousandth place)}$

$\text {If the number is 5 or more you raise the score. Meaning you add 1 to the}$ $\text {thousandth place. If the number is 4 or lower you keep the number the same.}$

$\text {6 is greater than 5. So this means you add 1 to 8 and it becomes 9. Every}$ $\text {number behind it becomes 0.}$

$\text {Your Answer Would Be:}$

$\huge\boxed {\text {6.7090 or 6.709}}$

$\text {Best of Luck!}$
