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.

A. imagine that you are one of the people who left the luncheon with a contagious disease and interacted with an average of 9 di
shusha [124]

1.       In line with the test each person who came into interaction with the infected person will become infected also. With this information, the calculation would be: 9 people each day for 7days would be equivalent to 9 x 7 which equals 63 people.

2.       Here were 7 other people in the experiment if patient zero is left out. If each person intermingled with 6 different people every day in 7 days then the calculation would be: 7 people infected x 6 new people = 42 infected people each day

42 new people every day x 7 days = 294 infected persons.

The coordinates of points A
Svetllana [295]

Answer:

Distance=13.60

Step-by-step explanation:

The Distance between the two points in coordinate system is find by using the distance formula.

If two points (x_1,y_1) and (x_2,y_2) are given:

Distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

For the points:

                     (-7, 5)\\ and \\(4, -3)

Distance=\sqrt{(4-(-7))^2+(-3-5)^2}\\\\ =\sqrt{(4+7)^2+(-8)^2} \\\\=\sqrt{11^2+(-8)^2} \\\\=\sqrt{121+64}\\\\ =\sqrt{185}\\\\ =13.60

The distance between the points is 13.60
