- 0.78 as a simplified fraction is 39/50
Fractions are numbers that are represented as the quotient of two integers
From the table, we have the following measurements
39/50 inch, 4/5 inch, 76/99 inch, 1/2 inch, 26/33 inch, 9/10 inch, 2/3 inch and 7/9 inch
Convert the fractions to decimal
0.78 inch, 0.80 inch, 0.77 inch, 0.50 inch, 0.78 inch, 0.90 inch, 0.67 inch and 0.78 inch
From the list of measurements,
3 lengths are less than 0.78 inch wide
This is less than half the number of rulers (i.e 4)
Hence, the supervisor does not need to call someone
When the fractions are converted to decimal, we have:
This means that:
0.78 as a simplified fraction is 39/50
