In what situation can you use only multiplication to find equivalent fractions to a given fraction given example?

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 \frac{4}{8}

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

\frac{4\times8}{8\times8}\:=\:\frac{32}{64}

Geometry homework help??? Pooters and Dooters were walking across a bridge one day, minding their own business. They knew that a train was due to come across that bridge soon, but they thought they could make it. It was a nice sunny day, and there was a great view from the bridge, so they walked very slowly, enjoying the view and savoring the warmth of the spring day. They were one-third of the way across the bridge, when the sound of a train whistle brought them instantly back to reality. Looking back over their shoulders, they saw a huge locomotive pulling tons of boxcars coming directly at them at 24 miles per hour! Using all their powers of mathematical reasoning, Pooters and Dooters immediately figured that they could run directly ahead and get to the far edge of the bridge at the exact same instant as the train. But they also knew that they could run back toward the train and get to the near end of the bridge just as the train got there. Basically, they knew they were dead meat. How fast do Pooters and Dooters run?

The explorer's running velocity will be 1/3 the velocity of the train, 45/3 = 15. From those issue statement, the train will a chance to be at the begin of the span The point when those voyagers have run 1/3 of the period of the span. In they run of the much end of the bridge, they will bring run 1/3 of the length of the span when those prepare achieves the close to wind. Beginning starting with those 1/3 point, they will make toward those 2/3 perspective At those prepare achieves those span. The prepare will travel the full period of the span in the the long haul it takes those voyagers to run those remaining 1/3. Accordingly the train must travel toward three times the running speed of the voyager. Train = 45 mph, voyagers = 15 mph. The speed of P&D = 15 mph

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'!

Number 9:
-->Sorry but I can't answer it yet because you didn't say what his recipt is. I can help you once you tell me what's on the receipt :)

How is an inequality different from an equation? Give a real-world scenario in which you would write an inequality rather than an equation. you should provide a thoughtful response of your own

An inequality is a equation that uses one of the following symbols to show its value: less than, greater than, less than or equal to, or greater than or equal to the corresponding symbols are as follows <,>,<_, and>_ ( note: the lines in<_ and >_ go directly underneath the base symbols of < and > ) an example of when you would use an inequality wold be if in the case of a x<_y symbol you had a number :x that you did not know, all you knew was that it was equal to y or any number of a lesser value. 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)
