How to multiply and divide algebraic fractions

Alex787 [66]

Answer:

Step-by-step explanation:

Multiplying two algebraic fractions produces a new algebraic fraction. Multiply the two numerators to get the new numerator and multiply the two denominators to get the new denominator. Then simplify by reducing the new fraction to lowest terms.

for example:

$\frac{x}{y} \\$ × $\frac{a}{b}$ = $\frac{xa}{yb}$

Division of algebraic fractions

The procedure for dividing algebraic fractions is the same as the procedure for dividing common fractions. Replace the division by a fraction by the multiplication by the reciprocal of that fraction, like this. Then carry out the multiplication of the two fractions as described above.

for example:

$\frac{\frac{a}{b} }{\frac{x}{y} }$

can be written as

$\frac{a}{b}$ × $\frac{x}{y}$ = $\frac{ax}{by}$

You cut off half of a strip of paper. then you cut half of the piece was left. then you cut half of the remaining piece.

lianna [129]

Answer:

The fraction of the original strip left is $\frac{1}{8}$ .

Step-by-step explanation:

We have that,

A strip of paper is cut in $\frac{1}{2}$ . So, the strip of paper left is $\frac{1}{2}$ .

Now, again the remaining part is cut in half. The part left will be $\frac{1/2}{2}$ i.e. $\frac{1}{4}$ .

Finally, the remaining part is again cut in half.

We get, the final part of the paper remaining is $\frac{1/4}{2}$ i.e. $\frac{1}{8}$ .

So, the fraction of the original strip left is $\frac{1}{8}$ .

In RSM camp, there are four counselors for every fifty seven students and three teachers for every five counselors.

Ray Of Light [21]

Answer:

Students : Counselors : Teachers = 285: 20 : 12

Step-by-step explanation:

In the camp, the ratio of:

( C: S ) Counselors : Students is 4 : 57

( T: C ) Teachers : Counselors is 3 : 5

To determine the ratio of - Students : Counselors : Teachers

Here given - C : S = 4 : 57

Multiplying both sides by 5, we get

C: S = 4 x 5 : 57 x 5 = 20 : 285

So, for every 20 counselors, there are 285 students ...... (1)

Similarly, given Teachers : Counselors is 3 : 5

Multiplying both sides by 4, we get

T : C = 3 x 4 : 5 x 4 = 12 : 20

So, for every 12 teachers, there are 20 Counselors ...... (2)

Hence, in both equation 1 and 2 the number of counselors is same = 20 .

Hence, both the ratios acne be combined.

So we get C : S = 20 : 285 and T : C = 12: 20

Inverting the values

⇒ S : C = 285 : 20 and C : T = 20 : 12

or, S : C : T = 285: 20 : 12

or, Students : Counselors : Teachers = 285: 20 : 12

Hence, for every 285 students there are 20 counselors and 12 teachers.
