Paul receives 2 portions, which equals to 7.9 * 2 = 15.8
Colin receives 3 portions , this equals to 7.9 * 3 = 23.7
the difference between the 2 portions is 23.7 - 15.8 = 7.9
hence, Colin receives £7.9 over Paul
Given:
The shape is a circle
Radius = 14 cm
To find:
The area and perimeter of the circle
Solution:
The value of π = 3.14
Area of the circle = πr²
= 3.14 × 14²
= 615.44 cm²
The area of the circle is 615.44 cm².
Perimeter of the circle = 2πr
= 2 × 3.14 × 14
= 87.92 cm
The perimeter of the circle is 87.92 cm.
If "4/2/7" is all we have to work with, then PEMDAS rules will save the day. Do the division from left to right.
4/2 becomes 2. Then we have 2/7, a proper fraction. I don't see where an improper fraction would come from in this case.
4 to the second power in standard notation is 400/1.
