Explain in sentences how you can add or subtract two fractions with common denominators?

Mathematics

If two fractions have the same denominators, then just simply add up the numerators together and keep the denominator.

Examples:

\frac{4}{10} +  \frac{5}{10} =  \frac{9}{10}

\frac{10}{12} - \frac{2}{12} = \frac{8}{12}

Solve the proportion. i need help.<br> x+3/6=8/3<br><br> x=?
stellarik [79]

Answer:

x = 2 1/6 (13/6)

Step-by-step explanation:

to solve the proportion you must first find the LCF or least common factor

that is 6

so turn 8/3 into 16/6 by multiplying it by 2/2

x + 3/6 = 16/6

then you subtract 3/6 from both sides

x = 13/6

x is 2 1/6

What is 103.468liters of water rounded to the nearest liter
Minchanka [31]
By rounding to the nearest liter, the question is asking us to round to the nearest whole number (get rid of any numbers after the decimal point). This means that we want the last number of our answer to be the number just to the left of the decimal point, which is a 3. 

To determine if we should leave the number or round it up, we look to the number to the right of the 3 which is a 4. Because 4 is less than 5, we do not round up. Therefore, the answer would be 103 liters. 

I hope this helps.

On a piece of paper, use a protractor and a ruler to construct △ABC with AB=8 cm , m∠A=70° , and m∠B=55° . What is AC ?
trapecia [35]

Answer: C) 8 cm


Step-by-step explanation:

Given: In △ABC  AB=8 cm , m∠A=70° , and m∠B=55° .

The angle sum property of triangle says that the sum of all interior angles in a triangle is equals to 180°.

⇒ m∠A+m∠B+m∠C=180°

⇒70°+55°+m∠C=180°

⇒m∠C=180°-125°

⇒m∠C=55°

Now, in △ABC m∠C= m∠B= 55°

⇒AB=AC [∵ Sides opposite to equal angles of a triangle are equal]

⇒ AC= 8 cm.
