What is addition of two fractions?

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Total number of yards of ribbon

= 5/6 + 9/10

LCM of denominators 6 and 10 is 30

Now, 25/30 + 27/30

= 52/30

= 1 (22)/(30) =1(11)/(15)

Therefore, the total length of the purple ribbon and pink ribbon is 1(11)/(15).

add 5/6 and 9/10
first look for a common denominator....that's....30
so now the fractions are 25/30 + 27/30
add the numerators keep the common denominator.
52/30 in mixed number is 1 22/30, now reduce the fraction, divide by 2, so
1 11/15, so Noelle has 1 11/15 ribbon altogether.

which statement is true for the pair of fractions shown? A 4/6 is equal to 9/12. B 4/6 is less than 9/12 C 4/6 is greater than 10/12. D 4/6 is greater than 10/12​

Answers

To figure this out, we just need to simplify as much as we can for each problem, and then find a common denominator.

A

4/6 = 9/12

2/3 = 3/4

this is false

B

4/6 < 9/12

2/3 < 3/4

8/12 < 9/12

this is true, but let's look at the others just in case

C

4/6 > 10/12

2/3 > 5/6

4/6 > 5/6

this is false

D

It looks like C and D are the same. This means D is also false.

So B is the only true statement

Answer: B

What is bigger 2/3 or 4/5 or

Answers

4/5 is equal to 0.8 when you divide 4 by 5. 2/3 is 0.66 when you divide 2 by 3. So 4/5 is bigger than 2/3.
2/3 as a percent would be 80%
and 
4/5 as a percent would be 25% 

so your answer would be 2/3 is bigger than 4/5 

Factor each expression 77x+21

Answers

77x + 21

We need to find the common factor between the coefficient and the constant.

77 ÷ 7 = 11
21 ÷ 7 = 3

7(11x + 3) is the factor of 77x + 21.

7(11x + 3) can be expanded using the distributive property of multiplication.

7(11x) + 7(3) = 77x + 21

Garth estimated the height of the door to his classroom in meters .What is a reasonable estimate?

Answers

The height of a door will be around 6 feet and 8 inches, so about 7 feet. You will need to convert this to meters. To do this, you should first know that 1 meter = 3.28 feet. Now, divide 7 by 3.28:

7/3.28 = 2.134

So, a reasonable estimate would be 2 meters.
For this case, the first thing you should do is compare the height of the door with the height of a person.
 On average, a person's height is between the following values:
 1.40 meters - 1.80 meters
 Therefore, we must find an amount that is greater than the maximum amount of a person's height.
 Therefore, a reasonable measure for the height of the door is:
 2 meters
 Answer:
 
a reasonable estimate is 2 meters.
