2.
(a). 16/40 in its simplest form is:- 2/5.
(b). 24/42 in its simplest form is:- 4/7.
3.
(a) The fractions ¾, 5/6, 7/9 as equivalent fractions with denominator 36 are as follows:
3/4= 27/36
5/6= 30/36
7/9= 28/36
(b) Given that
Total tickets sold by sporting event:- 1,20,000
Tickets sold at premium price:- 24,000
Tickets sold at standard price:- 62,000
Remaining tickets sold at discounted price let us assume that is 'x'
1,20,000= 24,000+62,000+x
x= 34,000
% of x=(34,000/1,20,000)*100
% of x= 28.33%
Thus % of tickets sold at discounted price is 28.33%.
4. Given that Arianne paid two £50 notes for 2 jackets and got a change of
£12.50.
Total amount paid:- £100-£12.50
=£87.5
price of 1 jacket= £87.5/2
