Which number line shows the correct placement of 20%, 1/3, and 2/3?

BigorU [14]

Answer with Step-by-step explanation:

We are given that

20%

When we change percent into fraction we will divide the percent by 100

$\frac{20}{100}=\frac{1}{5}$

$\frac{1}{3}$

$\frac{2}{3}$

We have to find the line which shows the correct placement of given numbers.

Lcm(3,5)=15

$\frac{1\times 3}{5\times 3}=\frac{3}{15}$

$\frac{1\times 5}{3\times 5}=\frac{5}{15}$

$\frac{2\times 5}{3\times 5}=\frac{10}{15}$

Answer : 110 degree

To find angle 1 , we apply outside angle theorem Lets name each point Measurement of arc EF=280 degrees

Measurement of arc GH = 60

Angle D = angle 1

Please refer to the theorem attached below

$angle D = \frac{arc(EF)-arc(GH)}{2}$

Now we plug in the values

$angle 1 = \frac{280-60}{2}$

angle 1 = 110

Measurement of angle 1 = 110 degrees
