Hint:
Fractions are referred to as the components of a whole in mathematics. A single object or a collection of objects might be the entire. A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the lower part represents the denominator and the top part the numerator.
We have given two fractions and we have to find the sum.
The correct answer is:
In general, the whole can be any particular thing or value, and the fraction might be a portion of any quantity out of it. The top and bottom numbers of a fraction are explained by the fundamentals of fractions. Fractions are further broken down into various categories based on the characteristics of the numerator and denominator.
As follows:
- Proper fractions
- Improper fractions
- Mixed fractions
- Like fractions
- Unlike fractions
- Equivalent fractions
Estimating sums and differences of fractions to the nearest 1/2:
- Fractions < 1/4 are rounded down to 0
- Fractions ≥ 1/4 and ≤ 3/4 are rounded to 1/2
- Fractions > 3/4 are rounded up to 1
Here the fraction that we have given is 
and , we have to round them off near to 0, , or 1.
So after looking at these numbers we can round them off as follows:
can be rounded to 0
can be rounded to
Now adding the rounded-off numbers, we get:
0 + =
The numerical numbers that make up a fraction of the whole are called fractions. A whole can be a single item or a collection of items. A fraction is represented as a/b, where a and b are the numerator and denominator, respectively. Here we were given to find the sum of two fractional numbers after rounding them off, the final answer is 1/2.
