The mustard color is used to highlight everything in the numerator of the main fraction
The purple color is used to highlight everything in the denominator of the main fraction
'a', 'b', 'c', and 'd' are all variables
Compare the example with numbers to the first example with variables

1. 'a', 'b', and 'c' are all variables in this case
2. 'a' is the numerator of the fraction 'a over b'
3. 'b' is the denominator of the fraction 'a over b'
4. The fraction 'a over b' is the numerator in the main fraction 'a over b, divided by c'
1. The main fraction bar is between 'a/b' and 'c'
1. 'a', 'b', 'c', and 'd' are all variables in this case
1. 'a' is the numerator in the simple fraction 'a/b'
2. 'b' is the denominator in the simple fraction 'a/b'
1. 'c' is the numerator in the simple fraction 'c/d'
2. 'd' is the denominator in the simple fraction 'c/d'
1. '2' is the numerator in the simple fraction '2/3'
2. '3' is the denominator in the simple fraction '2/3'
1. '2' is the numerator in the simple fraction '2/5'
2. '5' is the denominator in the simple fraction '2/5'
3. '6' is the numerator in the simple fraction '6/7'
4. '7' is the denominator in the simple fraction '6/7'
5. '2/5' is the main fraction's numerator
6. '6/7' is the main fraction's denominator
1. Locating the biggest fraction bar makes it easier to interpret a complex fraction
