Pencils come in packages of 10. Erasers come in packages of 12. Phillip want to purchase the smallest number of pencils and erasers so that he will have exactly 1 erasers per pencil. How many packages of pencils and erasers should Phillip buy

6 packages of pencils

5 packages of erasers

Step-by-step explanation:

we need to find the LCM of 10 and 12, which is 60

because 60 is divisible by both 10 and 12

60/10 = 6 packages of pencils

60/12 = 5 packages of erasers

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
