Convert mixed number to improper fraction

12 and 1 over 412

= ( 12 × 4 ) over 4

12 × 4

+ 1 over 4

= ( 48 + 1 ) over 4

48 + 1

= 49 over 4

Step 1 of 2: Divide, sub-step b: Divide.

Divide

49 over 4

÷ 7 over 8

= 49 over 4

× 8 over 7

= ( 49 × 8 ) over ( 4 × 7 )

49 × 8

4 × 7

= 392 over 28

Selma cannot remember her locker number! She knows that her locker number is prime, and that it is a factor of 435. What are all

tatuchka [14]

Answer:

Possible locker numbers for Selma are: 3, 5 and 29

Step-by-step explanation:

First of all, let us have a look at the definition of a prime number.

A <em>prime number</em> is a number which is divisible either by 1 or the number itself.

No other number divides the prime number other than 1 and the number itself.

Now, let us factorize the given number 435 and let us observe the what all possibilities are there.

$435 = 3\times 145$

Factorizing 145 further:

$435 = 3\times 5\times 29$

No further factors are possible.

Therefore 3, 5 and 29 are the prime factors of 435.

So, the answer is:

Possible locker numbers for Selma are: 3, 5 and 29

When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88

Natali5045456 [20]

Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2.

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!
