The Japanese 5 yen coin has a hole in the middle. If the diameter of the coin is 22 mm and the diameter of the hole is 5 mm, how
would you calculate in terms of es002-1.jpg how much longer the outer edge is than the inner edge?
2 answers:
To help you understand the problem, illustrate it first like that shown in the picture. What is asked is the distance between the outer edge and the inner edge (represented by the green arrow). That distance could be determined by getting the difference of the red and blue arrows, which represent the radii of the hole and the coin, respectively.
Thus,
distance = (22/2) - (5/2) = 8.5 mm
Thus,
distance = (22/2) - (5/2) = 8.5 mm

Step-by-step explanation:
to divide 2 fractions follow the procedure
• Leave the first fraction
• Change division to multiplication
• Turn the second fraction upside down
• Simplify by cancelling common factors, if possible
÷
= ×
(cancel 6 and 9 by 3 )
= ×

= ← in simplest form
The fraction is in simplest form when no factor apart from 1 divides into the numerator/ denominator
