3a) 3:1 or 3/1
3b) 3:4 or 3/4
4) 125 pages a day
5) 10 skittle per ounce in a bag
6) Market: $23.60/5= $4.72*7= $33.04, Orchard: $32.76/7= $4.68*5= $23.40, Which? Orchard because it is cheaper to buy 7 there than to buy 7 at market place because it is $00.30 cents cheaper at Orchard
7) Because money is always on top of time, amount, weight, etc.
You can just multiply the top and the bottom by the same number, and you will get equivalent fractions.
Step-by-step explanation:
✰ 
- AD = 15 , AB = 8 ,
DAB
✰ 
- Height & Area of the given parallelogram
✰ 
In right angled triangle ABE :
- Hypotenuse ( h ) = 8
- Perpendicular ( p ) = h [ height ]
= 20°
Now , Using trigonometric ratio :

Plug the known values :
⟶ 
⟶ 
⟶ 
⟶ 
Now , We have :
- Base ( b ) = 15
- Height ( h ) = 2.72
Finding the area of a parallelogram whose base and height are 15 and 2.72 respectively :
❀ 
⟶ 
⟶ 
Hence , Our final answer :
