2/5 - 1/3 (simplified if possible)

Mathematics
1 answer:
Kipish [7]2 years ago
7 0

Answer:

1/15

Step-by-step explanation:

(1).   <em>Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD (Least Common Denominator). </em>

So lets do step one now, the LCD is 15 so we have to make both denominators agree on one number, so 15 is the number both denominators agree on.

Solve:

2*3/5*3 - 1*5/3*5

(2). <em>Complete the multiplication.</em>

6/15 - 5/15

(3). <em>The two fractions now have like denominators so you can subtract the numerators.</em>

6 - 5 / 15 - 15 = 1/15

*Pro tip:

<em>The denominator doesn't change and stays the same. So you don't </em>

<em>subtract the 15 by 15.</em>

(4). <em>Then you'll get the answer and then if you can simplify then simplify.</em>

<em />

The Answer is 1/15, and cannot be simplified.

So the answer is 1/15

Hope this helps!

a satelite moves at the speed of 27,000 kilometers per hour what 4 number could be the actually speed of the satelite
Anvisha [2.4K]
If the satellite moves at a speed of 27,000 km p/h, your answer depends on the question.

This could be written in an algebraic expression, such as:

27,000x = S                 [for S stands for the ultimate speed of the satellite]

Of course, if this is a 3rd grade level question, I highly doubt they have even gotten started to including the alphabet into math. 

So, I would suggest plugging 4 into X.
To explain this to her, just say that the speed needs to be multiplied by the amount of hours it has traveled. (I got 4 because there is a '4' in the question instead of 'for').

Meaning,  
27,000 x 4 = 108,000 km per 4 hours

If her teacher decides to ask why that number, have her explain the question did not make sense so she plugged in a 4 to find an answer to a certain amount of hours. 

Hope that helps a bit with the confusion!

Bingel [31]

9514 1404 393

Answer:

  15/22 peso/m^2 ≈ 0.68182 peso/m^2

Step-by-step explanation:

The area is the product of the dimensions. 1 km = 1000 m.

  A = (550 m)(550·1000 m) = 302,500,000 m^2

The price per square meter is ...

  206,250,000/302,500,000 peso/m^2

  = 15/22 peso/m^2 ≈ 0.68182 peso/m^2
