Let x be the unit part, so the parts will be 1x, 2x, and 4x, and we'll have:
x + 2x + 4x = 63
7x = 63
x = 9
2x = 2 x 9 = 18
4x = 4 x 9 = 36
Thus, we can divide 63 kg in the ratio 1: 2: 4 as 9 kg, 18 kg, and 36 kg.

If you start with a ratio in the form p/q and want a ratio with a denominator of 1, simply divided p by q. So suppose you are given the ratio 35/10 (so that p = 35, q = 10). Then divide 35 by 10 which gives 3.5. So the units ratio is 3.5:1 or (7/2):1
1/2
Ah, ratios are just like happy little trees in a painting. To find an equivalent ratio for 7 to 1, you can simply multiply or divide both numbers by the same amount. For example, an equivalent ratio could be 14 to 2, or 21 to 3. Just remember, there are many ways to express the same ratio, so feel free to explore and find the one that brings you the most joy.
A ratio of 6:2 could be simplified to 3:1.
divide both numbers by a common denominator, e.g. 2, such that the ratio becomes 3:5.
