Question

how do you evaluate 20/6 - 2/3

Answer 1

Answer:

  8/3  or  2 2/3

Step-by-step explanation:

We do sums and differences of fractions by giving them a common denominator, then finding the sum or difference of the numerators. Here, you can reduce the first fraction to 10/3, so it will have the same denominator as the second fraction.

Now, you have ...

$\dfrac{10}{3}-\dfrac{2}{3}=\dfrac{10-2}{3}=\dfrac{8}{3}\\\\=\dfrac{2\cdot 3+2}{3}=2\frac{2}{3}$

___

If you're really stumped, you can have your calculator do it.

Answer 2

The required value of the given expression 20/6 - 2/3 is 8/3

Equations are expressions separated by equal signs

Given the expressions,

20/6 - 2/3

We need to first find the LCM of 6 and 3. Find the factors first as shown:

6 = 2 * 3

3 = 1* 3

Since the 3 can go in  both 3 and 6, hence the LCM will be 6

We are to find the difference in the fractions as shown:

$\frac{20}{6} - \frac{2}{3}\\\frac{20-2(2)}{6}\\\frac{20-4}{6}\\\frac{16}{6}\\\frac{8}{3}$

Hence the required value of the given expression is 8/3
