Answer:

70.

Step-by-step explanation:

Given : 5,514÷82

To find : use compatible numbers to estimate the quotient .

Solution : We have given 5,514÷82

Step 1: Find compatible numbers.

Compatible number : Compatible numbers are numbers that are close to the numbers they're replacing that divide evenly into each other.

Here, 5, 514

Estimate of 5, 514 is 5600.

Now estimate of 82 is 80.

Step 2: Divide the 5600 ÷ 80.

Step 3 : Cancel out zeroes

560 ÷ 8.

70.

So, the estimate of 5,514÷82 is 70.

Therefore, 70.

The answer is 67 because 67 x 82 is 5,494 which us close to 5,514

Answer:

13. 1/2, 5/8, 3/4

16. 7/12, 3/5, 2/3

Step-by-step explanation:

make them have the same denominator.

13) 1/2 x 4 = 4/8, 5/8, 3/4 x 2= 6/8

16) Grab two fractions let's say 3/5 and 2/3

Multiply 3/5 denominator (5) with 2/3 numerator (2)

It's 10 and place it above the number you multiplied the numerator from so it's above 2/3. Do it again but with 2/3 denominator (3) and 3/5 numerator (3). Multiply 3 and 3 you get 9. Place the 9 above 3/5. We know that 9 is less than 10 so 3/5 is less than 2/3. You can do this with any two fractions.

SOLUTION

From the question given the following statements to prove are correct, then the last part

$\Delta RSU\cong\Delta TSV$

The reason is Side-side-side triangle theorem

This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.

Hence the answer is Side-side-side triangle theorem

How many times does 9 go int 67

AnnZ [28]

°° Awesome question!

I'll show you how to solve this kind of question:

First, you can multiply 9 times any number to see if it's smaller than 67. If it is, it is OK to keep multiplying 9 by more numbers. Let's try this!

9 × 1 obviously equals 9, so we can keep going up.

9 × 2 = 18. Not quite there yet!

Sometimes it is OK for you to skip some numbers, Watch:

9 × 5 = 45. We can keep going. At this point you don't need to go backwards and do 9 × 3 or 9 × 4, because the products will only get farther away from 67.

9 × 6 = 54. We're getting closer!

Let's try to skip one number:

9 × 8 = 72 - HOLD UP! Oh no! We went over a little too much!

Let's try a number in between 6 and 8 - That would be 7, right?

9 × 7 = 63 - We were right on point! Obviously you can't multiply 9 by 8 again because you would get a bigger number - the 72.

__________________________________________________________

That was just one way to go about it, but there's another way, too!

You can divide 9 by 67 and see what you get. You may have a remainder, but you can just throw that out the window when we're all done:

9 ÷ 67 = 7.4444444444444444 The 4 just repeats on and on again, and we don't want that. So just throw those 4's out the window so you're left with 7.

Based on all this work, 9 goes into 67 7 times.
