Answer:

3^-1, square root of 9, -0.25, and 0.6

Step-by-step explanation:

Rational numbers are numbers that you can turn into fractions.

3^-1 = 0.3333333333... which is also known as 1/3

square root of 9 = 3, which can be written as 3/1

-0.25 can be written as -1/4

0.66666666... = 2/3

Claire Drew model of 5/10 explain how Claire could change her model to show how many hundreds are in 5/10 I know this is like my

natta225 [31]

Answer:

There are 0.005 hundreds in 5/10.

Step-by-step explanation:

Claire drew model of 5/10

We want to know how many hundreds are in 5/10.

Let us use an obvious example.

There are three 2's in 6 right?

Suppose we didn't know this, and we are told to find how many 2's are in 6, we get this by representing this in an algebraic expression as:

There are x 2's in 6. This can be written as

2x = 6

Solving for x, by dividing both sides by 2, we have the number of 2's that are in 6.

x = 6/2 = 3.

Now, to our work

We want to find how many hundreds are in 5/10. We solve the equation

100x = 5/10

x = 5/1000 = 0.005

There are 0.005 hundreds in 5/10.

Neko [114]

Answer:

-2/3, -0.6, 0.2, 1/2, 5/8

Step-by-step explanation:

What you do is you have to make them into decimals.

-0.6 and 0.2 are already in decimals.

-2/3 as a decimal is -0.667

1/2 as a decimal is 0.5

5/8 as a decimal is 0.625

-2/3, -0.6, 0.2, 1/2, 5/8 is your answer.
