Upper Tolerance
Remark
The 11/16 is the only thing that will be affected. The three won't go up or down when we add 1/64 so we should just work with the 11/16. We need only add 11/16 and 1/64 together to see what the upper range is. Later on we can add 3 into the mix.
Solution
<u>Upper Limit</u>
Now change the 11/16 into 64. Multiply numerator and denominator or 11/16 by 4
Which results in
With a final result for the fractions of 45/64
So the upper tolerance = 3 45/64
<u>Lower Tolerance</u>
Just follow the same steps as you did for the upper tolerance except you subtract 1/64 like this.
Your answer should be 3 and 43/64
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we know that irrational numbers are those real number which cannot be written in form.
Rational numbers are those real numbers which can be written in form.
Inverse property of multiplication is that property in which we write a number in reciprocal form .
Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.
Hence, belongs to rational numbers sets and inverse property of multiplication sets.
Therefore, Option 'B' and 'C' are correct.
So firstly, square root 9a^2 and 49:
Next, combine like terms, and your answer will be , or the third option.
