Question 1062678: Separate 72 into 2 parts which are in 4:5 ratio.
My attempt:
Let x = smaller part, then 72 - x = larger part.
x / 72 - x = 4/5
5x = 4(72 - x)
5x = 218 - 4x
5x + 4x = 218 - 4x + 4x
9x = 218
x = 24.222
24.222 / 72 - 24.222 = 4/5
24.222 / 2.97 = 4/5
5 * 24. 222 = 4 * 2.97
121.1 = 11.88
Where am I incorrect? Thanks.
