Please find my answer:

1.select fullname,part_description,sum(number_ordered) as total_parts from
(SELECT orders.order_date, sum(order_line.number_ordered) Parts_per_Day FROM orders, order_line WHERE orders.order_number = order_line.order_number GROUP BY orders.order_date ORDER BY orders.order_date asc;

2.select a.clast||' '||a.cfirst as fullname,a.street||' '||a.city||' '||a.state||' '||a.zip_code as address from customer a
join orders b on a.c_number=b.c_number
where b.order_date=TO_DATE('04-08-2013','dd-mm-yyyy');

3.select order_number,order_date,sum(quoted_price) from
(
select a.order_number,a.order_date,b.quoted_price from orders a
join order_line b on a.order_number=b.order_number
where a.order_date between TO_DATE('04-08-2013','dd-mm-yyyy') and TO_DATE('06-08-2013','dd-mm-yyyy')
) group by order_number,order_date;

4.select sr.commission_rate as AVG_RATE,sr.total_commission as MAX_COMMISSION from sales_rep sr
join customer c on sr.slsrep_number=c.slsrep_number
join orders ord on c.c_number=ord.c_number
join order_line ordl on ord.order_number=ordl.order_number
join part p on ordl.part_number=p.part_number and p.item_class='SG';

5.select a.warehouse_number,sum(b.number_ordered) as total_number from part a
join order_line b on a.part_number=b.part_number
group by a.warehouse_number;

6.select full_name,ord_num,sum(TQP) as TQP from
(
select sr.srlast||' '||sr.srfirst as full_name,ordl.order_number as ord_num,ordl.quoted_price as TQP
from sales_rep sr
join customer c on sr.slsrep_number=c.slsrep_number
join orders ord on c.c_number=ord.c_number
join order_line ordl on ord.order_number=ordl.order_number
)
group by full_name,ord_num;

7.select part_number,part_description from part
