Answers:
In these exercices are ilustrated the representations of the fractions
2) Firstly, we have 3 equal segments, each one representing
, hence:
is 3 copies of
Let's prove it, taking into account we are adding fractions with the same denominator:
There are 4 equal parts that make a whole
Four copies of
make
or 1 whole
3) Here we have a line divided into four segments, each one of
. Hence:
This is
of a line.
is 4 lengths of
If we draw one more
we will have
or 1 whole.
Then:
5 lengths of
make
or 1 whole.
4) In this part the answer is in the attached image. If we have two equal segments, each one of
we will have as a result
.
If we add another
segment, we will have three segments of
, having as a result
