HOW IT WORKS

To simplify a ratio, divide both parts by the highest common factor. For example, 6:9 becomes 2:3.

6 : 9

simplifies to 2 : 3

8 : 12

simplifies to 2 : 3

10 : 25

simplifies to 2 : 5

100 : 50

simplifies to 2 : 1

SPLIT TOTALS

Divide money or quantities in proportion.

SHARING METHOD

Add the ratio parts together, then give each side its fraction of the total. A 2:1 split of 60 gives 40 and 20.

2 : 1

60 splits as 40 / 20

3 : 2

120 splits as 72 / 48

5 : 2

70 splits as 50 / 20
