Answers:
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 
Parenthesis are something you can use in math problems that mean anything inside of them is what you have to solve first. In PEMDAS P is parenthesis which means that is first.
I just realized I forgot a whole unit we did this year, but a(n)=5n-12
is the explicit form if that helps at all
<span>cube has six identical walls
96ft</span>²<span> : 6 = 6 ft</span>²<span> - </span>one wall surface
<span>pattern on the surface of the cube
</span>A = a²
a - <span>the edge of the cube
A = a</span>² ⇔ a=√A
a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³
