Question

Edward bought 3 pencils of equal price of $4.20. The price of each pencil is __________.

$- \frac{7}{5}$
$\frac{5}{7}$
$- \frac{5}{7}$
$\frac{7}{5}$

hint Hint:

To find the price of 1 pencil we will divide the price of 3 pencils by 3.

The correct answer is: $7 over 5$

STEP BY STEP SOLUTION
Price of 3 pencils = $4.20
Price of 1 pencil = $fraction numerator P r i c e space o f space 3 space p e n c i l s space over denominator 3 space p e n c i l s end fraction$
$4.20 space divided by space 3 fraction numerator 420 over denominator space 100 end fraction space divided by space 3 over 1 space equals space 420 over 100 space cross times space 1 third space equals space 420 over 300 space equals space 7 over 5$
