Answer: should be 1/2

Step-by-step explanation:

It’s been a while but I believe scaling the triangle by 1/2 will end with a reduction, a smaller triangle.

I know pretty sure anything equal and larger then 1 would make the triangle grow.

Please help me. I didn't get it

$\frac{3}{10}$ + $\frac{2}{5}$

Multiply the $\frac{2}{5}$ by 2 on both sides to get a common denominator of 10. You should end up with $\frac{4}{10}$ .

$\frac{3}{10}$ + $\frac{4}{10}$ = $\frac{7}{10}$

Get a common denominator between $\frac{7}{10}$ and $\frac{5}{15}$ to compare them -- a common denominator is 30. Multiply the $\frac{7}{10}$ by 3, and $\frac{5}{15}$ by 2.

$\frac{21}{30}$ and $\frac{10}{30}$
The $\frac{7}{10}$ is obviously much larger than $\frac{5}{15}$ .

Now look at the answers. Which are true?

B and E are easily seen as true, because we know that the total of $\frac{5}{15}$ is not reasonable/right.

The 2 statements that are true are (B) and (E).

Write the numbers in order from greatest to least. 7.982, 7.981, 8.782, 8.981

ziro4ka [17]

Answer:

Step-by-step explanation:

To order decimals is to subtract, line up, and comparing digits.

Comparing digits is a good way to order decimals for greatest to least.

(Most Understood.)

<h3>Comparing Decimals:</h3><h3 />

We could put numbers in any order to compare digits, but you should look closely:

Numbers can<u> Trick You.</u>
<u>Be wise, look closely.</u>
<u>If the digit is 0 for a number, the other number is greater if it's not 0.</u>

Lastly, <u>you (cannot) multiply, divide, add, or subtract.</u>

__________________________________________

First, we pick 2 numbers to compare, maybe 8.782 and 8.981.

We look at the digits for both numbers.

We see 8's, And 7 and 9, 9 is greater, so 8.<u>9</u>81 is the greatest and 8.<u>7</u>82 is the 2nd greatest.

<h3>8.981, 8.782, ?.???, ?.??? Is Our Order so far.</h3>

Our last 2 numbers are 7.981 and 7.982,

We look at the digits for both numbers.

We see 7's, we see 9's, and we see 8's, but 1 and 2. 2 is greater so 7.98<u>2</u> is the 3rd greatest and 7.98<u>1</u> is the least.

<h3>Our order is: 8.981, 8.782, 7.982, 7.981.</h3><h3>We checked it by comparing wisely. (√ Means Check)</h3>

Best of Luck to you.
