Question

if we divide 729 int two parts in the ratio of 5:4, then the smallest part is equal to​

Answer 1

now the parts will be 5x and 4x hence 5x+4x = 729 hence 9x = 729 = x 81

now lowest part = 4x = 324

Answer 2

Answer:

5:4

5x+4x=9x=729

9x=729

x=729/9= 81

so, the smallest part will be 81*4 = 324...
