Write two ratios of 2 / 3, the ratio of () and () is ()

Write two ratios of 2 / 3, (2:3) and (4:6), and the ratio is (2:3 = 4:6)
The answer is not unique

There are two ratios whose ratios are equal to 2 / 3. The latter term of the first ratio and the former term of the second ratio are both 6. The ratio of these two ratios is 6

The preceding term of the first ratio is 6 × 2 / 3 = 4
The latter term of the second ratio is 6 / 2 / 3 = 9
The ratio is 4:6 = 6:9

Write two ratios whose ratios are two fifths and make up the ratio

2: 5,4:10, the composition ratio is 8:20:50
