Mrs. Dodson has a jar full of pennies and quarters. There are 120 coins in the jar worth a
total of $12. Find the number of pennies and the number of quarters in the jar.

10.

Step-by-step explanation:

DIVISION. 120/12.

That is hard! Here's a trick.

12x9= 99=9=108. Or 12x6=66+6=72.

We will stick with 12x9,  that equals 108.

We should add another 12 until we get to 120.

108+12=120. That is 10 times. The trick was...

dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.

44 then and another 4. That is 48. So 12x4=48.

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2
