This might be a bit hard ! But you will get it ! Don’t worry
In this equation h is already given , practically making it arithmetic
So h = 2/7
So 6/1 - 2/7 divided by 3/8
By Bodmas and fraction reciprocal rule
2/7 divided by 3/8 comes first
In division of fraction , the second number will be reversed or also known as reciprocal
So 2. 8
— X. ——
7. 3
Which becomes
16/21
So 6/1 - 16/21
So by lcm 6/1 becomes 126/21
So (126 - 16) /21
110/21
Problem solved !
