Answer:
Hi there! Your answer is =4 3/4
Step-by-step explanation:
I hope this helps :]
Alright. First I did 1/4 + 1/6. I got 5 1/2
Then I did 5 1/2 + -3/4. Because it is negitive I had to go down so that is why it is lower. if you need a more detailed explanation ill gladly tell you!
1/4+1/6=?
Find the LCD of 1/4 and 1/6 and rewrite to solve with the equivalent fractions.
CD = 12
3 1 /2+2 1/2=5 1/2
Solution by Formulas
Using the given fractions,
1/4+1/6
Applying the fractions formula for addition,
=(1×6)+(1×4)4×6
=6+4 2/4
=10 2/4
Simplifying 10/24, the answer is
=5 1/2L
if you want the other one tell me!

If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of s? triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals p, EA equals r, CD equals q, DB equals t, ED equals s, and AB equals u s equals p over q s = one halfu s equals q over p s = 2u
The side ED is a midsegment of the triangle ΔABC, therefore, the length of
ED is half the length of AB.
[tex]\displaystyle The \ expression \ that \ represent \ the \ value \ of \ s \ is; \ s = \frac{1}{2} \cdot u[/tex]
s = one half uReasons:
The given parameters are;
In ΔABC, point E is the midpoint of AC
The midpoint of BC is the point D
Segment ED = s
Segment CE = p
Segment EA = r
Segment CD = q
Segment DB = t
Segment ED = s
Segment AB = u
Required;
The expression that represents the value of s
Solution:
CE = 0.5 × AC Definition of midpoint
CD = 0.5 × CB Definition of midpoint
Therefore;
Therefore, we have;
[tex]\displaystyle \frac{CE}{AC} = \mathbf{\frac{CD}{CB}} = 0.5[/tex]
Therefore, given that ∠C ≅ ∠C, by reflexive property, we have;
ΔABC is similar to ΔCDE by Side-Angle-Side similarity
Which gives;
[tex]\displaystyle \frac{CE}{AC} = \frac{CD}{CB} = \mathbf{\frac{ED}{AB} } = 0.5 = \frac{1}{2}[/tex]
ED = s and AB = u which gives;
[tex]\displaystyle \frac{ED}{AB} =\frac{s}{u} = 0.5 = \frac{1}{2}[/tex]
[tex]\displaystyle \frac{s}{u} = \frac{1}{2}[/tex]
Which gives;
[tex]\displaystyle s = \mathbf{ \frac{1}{2} \times u}[/tex]
(The above relationship is given by the midsegment theorem)
Therefore;
The expression that represents the value of s is; s = one half u

2 1/7 divided by 2/7
__/7 divided by 2/7
__/7 x __/__ = ___
Answer:
the answer is 4 1/2
Step-by-step explanation:
first you have to turn your 2 1/7 into an improper fraction : 2x1+7, and you get 9/7.
then you divide 9/7 by 2/7 or you can also flip the second fraction and multiply : 9/7 divided by 2/7 turns into --- 9/7 x 7/2 so from here you cross simplify, you cant simplify 2 into 9 so no simplifying there but 7 can go into 7 once so you are left with 9/1 and 1/2 then multiply 9x1 and 1x2 and you get 9/2.
from here you turn your improper fraction into a proper fraction by seeing how many times 2 can go into 9 , which is 4 times (4 is the whole numbers) and you are left with 1 (numerator) over 2 (denominator)

a student needs 2/3 pound of modeling clay for a project. if each package has 1/8 pound of clay, how many packages of clay does the student need for his project
The student needs 16.3 packages of clay to complete his project
Data given;
Total amount of clay needed = 2/3 poundeach package = 1/8 poundTo solve this question, we just need to divide fractions.
Division of FractionsThis is done when the denominator divides the numerator. Often times, this also results in multiplication
To get the number of package the student needs, let's write an equation
[tex]2/3 = 1/8x[/tex]
where x = number of packages needed
[tex]\frac{2}{3} = \frac{1}{8}x\\ 2 * 8 = 3 * x\\ 16 =3x\\x = 16/3\\[/tex]
