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.

Define a variable, write equation, solve and answer the question.
Nostrana [21]

Answer:

I don't know if you want the beginning to so-

Variable - A unknown value represented by a set letter.

4x+6 = 26

(Incase: Subtract 6 from 6, and 6 from 26. 6 cancels out, and 26-6 is 20. Divide both sides by 4. And x=5)

And the answer to the question is: -27 is the smallest, and then the 3 consecutive numbers are -27, -28, and -29.
