How do I do percent ​

Simple

Step-by-step explanation:

Just remember this :

x / total into 100

What ever is there just multiply by hundred to make it percent but sometimes they will ask u tricky q so u need to rearrange this formula

I hope this is   wht u expected

For a fraction, make the fraction out of 100 or change it to a decimal

example: 1/20 = 5/100 = 5%

For a decimal, just multiply by 100 or change it to a fraction

example: 0.31 = 31%

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
