The answer is 'yes', but the 'other number' is always ' 1 '.

The definition of 'prime' number is the explanation.

A prime number is a number that has no factors except ' 1 ' and itself.

If it were a multiple of anything besides ' 1 ' and itself, it would not be

a 'prime' number.

QUESTION POSTED AT 14/12/2019 - 02:09 PM

**Answer:**

**Equivalent fraction are the fractions whose simplest term is equal to simplest term of original fraction.**

Equivalent fraction can be find using multiplication operation or division operation on numerator and denominator by same no.

⇒ **Multiplication is used when we are given with a fraction and we need to find an equivalent fraction whose numerator and denominator is greater than given fraction.**

**For example,**

Given fraction is

If **we need to find equivalent fraction whose denominator is 64 then we use multiplication operation.**

∵ Since Denominator of given fraction is 8 and denominator of equivalent fraction is 64. ⇒ **we need to multiply 8 with 8 to get 64**

So, if we multiply both numerator and denominator by 8 we get an equivalent fraction with denominator 64

Hey :)

Number 7:

-->Let's find the least common multiple of 4, 10, and 12 by listing again:

4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40... 60

10: 10, 20, 30, 40, 50, 60

12: 12, 24, 36, 48, 60

-->As you can see, the LCM is d or 60

* Just a random thought but did you accidently write 7 for the other one?

Number 8:

-->By factoring the expression, you would be finding a factor that both numbers share (usually the GCF) and divide the whole expression by that number:

"What is the GCF of 54 and 24?"

"6!"

--> So now that you know the GCF or just factor, you can divide the expression by it:

54a+24b

54a(/6)+24b(/6)

9a+4b

--> Sorry if this gets confusing but now you put the end result in parentheses with what you divided it by on the outside

6(9a+4b)

-->Or in other words, answer choice 'c'!

Say y was 3 x could be any number from 3 to negative infinity another more real life example might be you are charging someone for a service and their is a max price you are willing to charge say that price was $10 and you had some chriteria that decided the price or so the inequality would look something like 0<_x<_$10 ( the 0<_ x is because you probably won't pay to work)
