Answer:
we cananswer the questions by using BODMAS rule
we want want to solve the equations in the form BODMAS rule
B= we want to solve brackets first
O= we want to solve flower brackets second
D= we want to do division third
M=we want to do multiplication fourth
A= we want to do addition fifth
S= we want to do subtraction sixth
by following the sequence we want to do any problems
a= by rule want to do multiplication first because there is no brackets
2÷30-1÷12+4÷15
1÷15-1÷12+4÷15
5÷15-1÷12
1÷3-1÷12
by this we can solve b and c
sorry I have no time to solve B and C
