Move the decimal over 2 places to the right and divide by 100
2.75 mm = 275/100 mm
Simplify:
275/100 = 55/20 (we know both terms are divisible by 5)
55/20 = 11/4 (again, we know both terms are divisible by 5)
The answer is 11/4 mm (cannot be simplified any further)
An alternative way to approach this is to realize that 0.75 = 3/4
So 2+3/4 = 8/4+3/4 = 11/4
275mm equals 27.5cm
It is 275mm wide
It is 275 mm wide at the tread.
27.5cm (divide mm by 10)
3/32
27/10
3/8
8/10
9/10
35/1000
Anything over itself equals one.
this will equal to 48.10 which is very official
