How to express a mixed number as a percent

Make it an improper fraction and multiply by 100

Well a percent means out of a hundred

And a mixed number is

x e/y (example)

Now we know the whole number is already 1 and above so we know that’s already a 100%

Now we just need to add the other fraction to the 100%.

Thats it!

OR you can do convert the mixed number into an improper fraction.

From there make a proportion of the improper fraction equaling x/100

Now solve the proportion by cross multiplying.

Solve for x

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
