Order from least to greatest

inessss [21]

The order from the least to the greatest is $-\frac{26}{5}$ , $-5 . \overline{17}$ , $\sqrt{33}$ , and $\frac{37}{6}$ .

Step-by-step explanation:

Step 1:

We must determine each of the individual values to be able to arrange the given numbers.

$\frac{37}{6} = 6.166666,$

$-5 . \overline{17}$ means that so 1 and 7 in the decimal keep repeating so,

$-5 . \overline{17} = -5.17171717.$

$\sqrt{33} = 33^{\frac{1}{2} } = 5.7445,$ and

$-\frac{26}{5} = -5.2.$

Now that we have all the four values, we can arrange them in ascending order.

Step 2:

There are two negative numbers, the greater a negative number the lesser it is i.e. $-6 < -5.$

So the least value is $-\frac{26}{5}$ which is followed by $-5 . \overline{17}$ .

The other two are positive numbers. As $5.7445 > 6.1666$ so the highest number is $\frac{37}{6}$ .

So the order from the least to the greatest is $-\frac{26}{5}$ , $-5 . \overline{17}$ , $\sqrt{33}$ , and $\frac{37}{6}$ .

Solve for each expression by writing the solution in unit form and in standard form.

Sonja [21]

Answer:

Unit Form:

3 hundreds, 0 tens, 0 ones
5 thousands, 0 hundreds, 0 tens, 0 ones
9 thousands, 0 hundreds, 0 tens, 0 ones
7 ten thousands, 0 thousands, 0 hundreds, 0 tens, 0 ones

Standard Form:

300
5,000
9,000
70,000

Step-by-step explanation:

Here is how to write solutions to expressions in unit form:

Its important to note that unit form expands a standard form number into ones, tens, hundreds, and so on.

Take your first expression for example.

10 × 3 tens

Re-write this expression so that all terms are in standard form. The second term is 3 tens, which can be represented as thirty.

10 × 3 tens

10 × 30

Solve this expression. Multiply ten by thirty.

10 × 30

300

The expression is now represented in its simplest form. We can start to write it in unit form. Break up three hundred into its hundreds, tens, and ones.

300

3 hundreds, 00

3 hundreds, 0 tens, 0

3 hundreds, 0 tens, 0 ones

This shows that the solution to the first expression written in unit form is 3 hundreds, 0 tens, 0 ones.

We can continue to solve the following expressions in the same manner. Just in case you still need some help. Here is how you find the remaining three solutions in unit form.

Problem Two

5 hundreds × 10

500 × 10

5,000

5 thousands, 0 hundreds, 0 tens, 0 ones

Problem Three

9 ten thousands ÷ 10

90,000 ÷ 10

9,000

9 thousands, 0 hundreds, 0 tens, 0 ones

Problem Four

10 × 7 thousands

10 × 7,000

70,000

7 ten thousands, 0 thousands, 0 hundreds, 0 tens, 0 ones

Here's how to solve the second part of the problem:

This portion says we need to write the solution in standard form. It is important to remember that a number written in standard form will looks like an ordinary number, i.e. 76, 902, 474.

This means that under the category titled 'standard form' we must write the answer as the ordinary solution.
