How do you divide 5 1/4 line into three parts whose ratios are 1.2.3

1 + 2 + 3 = 6

To get parts in a ratio of 1 to 2 to 3, the parts are in the ratio of 1/6 to 2/6 to 3/6 of 5 1/4.

Change 5 1/4 into a fraction: 5 1/4 = 21/4

Now find 1/6 of 21/4, then find 2/6 of 21/4, then find 3/6 of 21/4.

1/6 * 21/4 = 21/24 = 7/8

2/6 * 21/4 = 1/3 * 21/4 = 21/12 = 7/4 = 1 3/4

3/6 * 21/4 = 1/2 * 21/4 = 21/8 = 2 5/8

The parts of 5 1/4 in a ratio of 1:2:3 are 7/8, 1 3/4, 2 5/8
