Let's take 1/5 as an example. Okay so percents are usually x/100. So what times 5 equals 100? 20! So we multiply both the top and bottom by 20. 1 x 20= 20 and 5 x 20= 100. So it would be 20/100 as a fraction. Now since a percent is out of 100, then you just take the 20 as a percent. The answer to this would be 20%. Now for numbers that don't easily go Into 100. Let us look at 2/3. You would have to divide 2 by 3 which is .6666. Now put decimal two places to the right. Percent is 66%

Hi ,  you have to divide the numerator and the denominator , if you get a decimal you just have to move the period 2 spaces to the right.
For example
3/8 -0.375
0.375 - 37.5

Drag a statement or reason to each box to complete this proof.
Pepsi [2]

In the given quadrilateral ABCD,

m\angle A=7x^{\circ} , m\angle B=5x^{\circ}, m\angle C=7x^{\circ} , m\angle D=5x^{\circ}  (Given)

m\angle A + m\angle B+ m\angle C+ m\angle D=360^{\circ}

(Sum of interior angles of a quadrilateral is 360 degrees)

7x\dot{^{\circ}} + 5x^{\circ}+ 7x\dot{^{\circ}} + 5x^{\circ}=360^{\circ}(Substitution Property)

24x^{\circ}=360\dot{^{\circ}} (Addition Property of Equality)

x=15^{\circ}
