Sagot :
- The estimate for the first expression is [tex]\frac{1}{2}[/tex].
- The estimate for the second expression is 1.
- The estimate for the third expression is 0.
Given the following expression:
- [tex]\frac{1}{8} + \frac{2}{5}[/tex]
- [tex]\frac{13}{14} -\frac{1}{10}[/tex]
- [tex]\frac{1}{12} + \frac{1}{20}[/tex]
To determine an estimate for each expression:
What is a fraction?
A fraction can be defined as a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.
The parts of a fraction
Generally, a fraction comprises two (2) main parts and these include:
- Numerator: it's the upper part of a fraction.
- Denominator: it's the lower part of a fraction.
In this exercise, we would simplify and estimate the given expressions as follows:
Note: An estimate simply means an approximate value.
a. [tex]\frac{1}{8} + \frac{2}{5}=\frac{5+16}{40}=\frac{21}{40}[/tex]
For the estimate:
[tex]\frac{1}{8} + \frac{2}{5}=\frac{1}{2}[/tex]
b. [tex]\frac{13}{14} -\frac{1}{10}=\frac{130-14}{140} =\frac{116}{140} =0.83[/tex]
For the estimate:
0.83 ≈ 1
c. [tex]\frac{1}{12} + \frac{1}{20}=\frac{5-3}{60} =\frac{2}{60} =0.03[/tex]
For the estimate:
0.03 ≈ 0
