Os números que não são racionais são os da opção C)
Greetings!
"Write and solve an equation to determine how many servings of this item ...exactly 45 grams of cholesterol"...
The
variable in this equation would be the
amount of servings she can eat of the items.
Lets represent this as

;

=amount of servings
The item has
30 mg of cholesterol and she wants to only consume
45 mg.
The equation would be:

Solve for
x.
Divide both sides by
30.

Simplify.

Alisa can consume
1.5 servings of the item each day.
Hope this helps.

60 percent of 264
=(60/100)*264
= (60*264)/100
= 15840/100=158.4

1. Rational/The sum of two rationals is always rational
2. Irrational/ the sum of a rational and an irrational is always irrational
3. Irrational/The product of a nonzero rational and an irrational is always irrational
4. Rational/The product of two rationals is always rational
Pretty much all the irrational numbers are the ones with radical signs over them and the rational numbers are the fractions and whole numbers. Once you identify the two numbers to be rational or irrational, you can then find your answer within the second part of the answers.
