Answer:
in any numerical computation; numerical values can only be rational numbers
Step-by-step explanation:
Any time a number is written down as a numerical value, it is a rational number. The numerical values we give to π or e or any root, logarithm, trig function, and polynomial solution are, of necessity, rational approximations to the true value. An "exact" value for an irrational number cannot be written down, so it must be approximated any time its numerical value is needed.
Answer:
- 
Step-by-step explanation:
Given
-
← divide numerator/ denominator by 14 )
= - 
Yes. J<span>amie's estimate seem reasonable.
This is because, when we expand the expression </span><span>1.43 x (-20/39) we get;
</span><span>1.43 x (-20/39) = -0.73333... (3 is repeating)
Her estimate was -0.75 while the actual answer is </span>-0.73333...
This is a good estimate since the difference is 0.016666.... which is negligible.
