2/3 + 3/4 

First, we need to find a common denominator.

2*4/3*4 = 8/12

3*3/4*3 = 9/12

Now add the numerators.

9+8 = 17

17/12 = 1 5/12

Answer: 1  5/12

5 * 3/4 = 

5/1 * 3/4 = 15/4

15/4 = 3  3/4

Answer: 3  3/4

2/3 + 3/4
For this, you want to cross multiply
To do this, you do the first numerator (2) multiplied by the second denominator (4), and the first denominator (3) multiplied by the second numerator (3).If you draw lines between the two numbers you are multiplying, a 'cross' is made. Add these two numbers together to make the new numerator. For the denominator, multiply the bottom two numbers.
Next simplify the new fraction (Follow attached  image)

5 x 3/4
This can be written as 5 x 3 / 4
5 x 3 = 15
15/4 = 3 3/4 or 3.75

A student thinks the sum of 4.3 and 8.4 is 12.7 because 4+8 is 12 and 3+4 is 7. The student then adds 3.7 and 2.6, then gets 5.13 because 3+2 is 5 and 6+7 is 13. Identify the mistake in the student's procedure and explain why the procedure won't always work.

Answers

The mistake is that when adding decimals, if the number is greater than 10 then you add one to the ones place and subtract ten from the decimal. So the answer should have been 6.3

I have this math question and im confused23=x-9;x=14
?
23=__-9
?
23=__

can you help me?

Answers

You are supposed to replace x with what we know and solve.
The answers would be 14 for the first and 23 for the second.

To solve, substitute the value of x, 14, into the equation then solve. However, I believe that you meant to make the - sign a + sign because that's the only way the statement would be true.

23 = x + 9 ; x=14
23 = 14 + 9
23 = 23

Numbers such as 1, 4, 9, 16, and 25 are called

Answers

They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25 
16 is 4 bc 4(4) is 16 
9 is 3 bc 3(3) is 9 
1 is 1 bc 1(1) is 1 
& so on & so forth

Darius created a factor tree and wrote the prime factorization of 60 shown here.A factor tree of 60. 60 branches to 4 and 15. 4 branches to 2 and 2. 15 branches to 3 and 5.


60 = 2 × 3 × 5

What is Darius’s error?

Answers

Answer: he needs to finish factoring the 4s.

Step-by-step explanation:

4x15 is 60, so that is right, 3x5 is 15, so that’s is right, 2x2 is 4, so that is right, but he didn’t finish factoring. 1x1 is 2, so he should have 1 and 1 coming from each 2 on the tree. Hope this helps.
