SOURCE: how to simplify ratios using scientific calculator fx-991ms

If you enter the ratios using the fraction entry key ( [a b/c] the
results will be displayed as fractions. And when the calculator
displays fractions they are always in their reduced form.

In general,
when you are manipulating fractions ( Pi/2 is no a fraction even if you
write it as one) you can try to simplify them by looking for the
greatest common factor (GCF) of the numerator and denominator. When you
simplify by the GCF the fraction that is left is in its reduced form.

A ratio can be simplified by dividing both sides of the ratio by the Highest Common Factor (HCF). The highest common factor is the largest number that goes into both numbers of your ratio. In example 1 you are asked to simplify the ratio 6:8. Here the HCF is 2 so divide both sides of the ratio by 2 to give 3:4.

You cannot simplify it further because the two numbers do not have a common divisor except 1

63=7*9

121=11^2

63=7*9

121=11^2

A ratio is a division of two quantities that may or may not have the same units. Example of a ratio: Speed =distance/time, specific gravity (density) =mass/volume.

Simplifying a fraction is writing it with the smallest numerator and denominator. In that case one says that the fraction is in its reduced form.

35/20=(5*7)/(5*4)=(5/5)*(7/4)=7/4

7/4 cannot be reduced further, so we say the reduced form of 35/20 is 7/4

If there are 40 total students, and 25 are boys, then (40-25) of them are girls, or 15.

That means the ratio of boys to girls is 25 to 15, or 25/15

This can be simplified by dividing by 5, so the ratio is 5/3

1/25 IS the ratio of 1 to 25. There is not much you can say about it.

Can it be reduced to simpler terms? No! because there no factor common to the numerator (1) and the denominator (25) which you can simplify.

So 1/25 is in its reduced form.

Case of the ratio 2/100

It is clear that we can write the numerator as 1*2. To hope to reduce the ratio to simpler terms we must be able to find a factor that is common to the numerator and the denominator.

Although 100 =1*100=2*50=4*25=4*5*5 it is clear that the only factors common to 2 and 100 are 1, and 2.

To take 1 amounts to doing nothing, but if we take 2 we can write

2/100= (2*1)/(2*50)

Simplifying by 2 (the two 2 cancel each other) we get

2/100=1/50

That is the reduced form.
