2a = 5b
2a/b = 5
a/b = 5/2
3b = 7c
b = 7c/3
b/c = 7/3
Now change the denominator for a/b and numerator for b/c to be the same, since they are both b. This is to make all 3 comparable.
The lowest common multiple of 2 and 7 is 14.
a/b = 5/2 = 35/14 (multiply by 7)
b/c = 7/3 = 14/6 (multiplied by 2)
So a : b : c = 35 : 14 : 6
2a/b = 5
a/b = 5/2
3b = 7c
b = 7c/3
b/c = 7/3
Now change the denominator for a/b and numerator for b/c to be the same, since they are both b. This is to make all 3 comparable.
The lowest common multiple of 2 and 7 is 14.
a/b = 5/2 = 35/14 (multiply by 7)
b/c = 7/3 = 14/6 (multiplied by 2)
So a : b : c = 35 : 14 : 6
