In these exercices are ilustrated the representations of the fractions
2) Firstly, we have 3 equal segments, each one representing , hence:
is <u>3</u> copies of
Let's prove it, taking into account we are adding fractions with the same denominator:
There are <u>4</u> equal parts that make a whole
Four copies of <u></u> make
or <u>1</u> whole
3) Here we have a line divided into four segments, each one of . Hence:
This is of a line.
is <u>4</u> lengths of
If we draw one more we will have
or 1 whole.
Then:
<u>5</u> lengths of make
or <u>1</u> 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
The table is attached as a figure
The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0
From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2
From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2
So, the picked three solutions are
y = 0 at x = 0
y = -2 at x = -1
y = 2 at x = 1
