Answer:

1/2 +0.5=1  and 3√16 + 3√16=6√16

Step-by-step explanation:

Rational numbers are numbers that can be written as fractions.  These include fractions, decimals, integers and whole numbers, or anything that can be simplified to one of these.

1/2 + 0.5 = 1 shows us a fraction added to a decimal that equals a whole number.  All three of these are rational numbers, so this shows that rational numbers are closed under addition.

3√16 + 3√16=6√16 contains a radical, which is only a rational number if it simplifies to one.  √16 = 4; this means we can rewrite this as

3(4) + 3(4) = 6(4)

This gives us

12 + 12 = 24

This is a true statement, and shows that rational numbers are closed under addition.

Slope is 1/4

Step-by-step explanation:

Count the rise over run from somewhere the line is matched up with a whole point, like 20 or 60. The next place the point is a whole (if starting from 20) is 60. Run is 4. The Rise from 20 to 60 is 1

Gerrie collects honey from a few
neonofarm [45]

The number of the cups of honey has she collected will be 52 and 2/3 cups.

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Gerrie collects honey from a few beehives.

She scoops out the honey with a small jar that holds 1/3 of a cup.

Over the last two weeks, Gerrie has filled this jar 158 times.

1 small jar = 1/3 cup

But we have done this for 158 times. Then we have

158 small jar = 158 x 1/3 cups

158 small jar = 52 and 2/3 cups

More about the ratio and the proportion link is given below.
