Zeph and Oliver have some pink markers and some black markers. The number of black markers Zeph has is equal to the number of pink markers Oliver has. ³₄ of Zeph's markers are pink and ¹₄ of Oliver's markers are black. There are a total of 120 pink markers. Find the total number of markers they have.

Zeph		Oliver		Total
Pink	Black	Pink	Black
	1x3	1x3
3x3	1x3	3x1	1x1
9 u	3 u	3 u	1 u	16 u

The number of Zeph's black markers and Oliver's pink markers is the same.

The number of Zeph's black markers is repeated. The number of Oliver's pink markers is repeated.  Make the number of Zeph's black markers and Oliver's pink markers the same.  LCM of 1 and 4 is 3.

Number of pink markers
= 9 u + 3 u
= 12 u

12 u = 120

1 u = 120 ÷ 12 = 10

Total number of markers
= 9 u + 3 u + 3 u + 1 u
= 16 u
= 16 x 10
= 160

Answer(s): 160
