A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key ch

Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question, and will be teaching you how to handle it on your own in the future.

We have 350 total keychains, in which 10% are yellow, 3/5 are green, and x are red. We will be solving for red, but we need to subtract 10% and 3/5 from 350.

So, let's find out how much 10% of 350 is.
Since 10% is equivalent to 1/10, we can divide 350 by 10 to find how many yellow key chains there are.
350 / 10 = 35.
There are 35 yellow key chains. We can subtract this from 350 to narrow it down.
350 - 35 = 315.

Now, let's find how much 3/5 of 350 is, and subtract it from our new number (315).

Divide 350 by 5, and then multiply that quotient by 3.
350 / 5 = 70.
70 x 3 = 210.

We have 210 green key chains. Now let's subtract that from 315. This will give us the remaining key chains - which are red.
315 - 210 = 105.

There are 105 red key chains.

I hope this helps!

100 POINTS PLEASE HELP ASAP!!!!<br> Explain the concept of using cancellation to reduce fractions.

Setler79 [48]

Explanation:

A "reduced" fraction is one that has mutually prime numerator and denominator. That is, the numerator and denominator have no common factors.

A fraction is "reduced" by canceling common factors from numerator and denominator. If "a" is a factor common to the numerator and denominator of a fraction, that fraction can be written with "a" canceled from each:

$\dfrac{ab}{ac}=\dfrac{a}{a}\cdot\dfrac{b}{c}=1\cdot\dfrac{b}{c}=\dfrac{b}{c}$

Here is a numerical example:

$\dfrac{2}{4}=\dfrac{2\cdot 1}{2\cdot 2}=\dfrac{2}{2}\cdot\dfrac{1}{2}=\dfrac{1}{2}$

__

A numerator factor and a denominator factor "cancel" because their ratio is 1, the identity element for multiplication. Anything times 1 is just that thing.
