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}

one gym membership charges $10 a month with a sign-up fee of $45. Another gym does not charge patrons a sign-up fee but costs $2
ss7ja [257]

After 3 months memberships will cost the same.

We have,

Cost of Membership of 1st gym = $ 10  per month

And, the Cost of the sign-up fee for 1st gym = $ 45

And,

Cost of Membership of  2nd gym =  $ 25 per month

And, the Cost of the sign-up fee of the 2nd gym = $ 0

Now,

Let the number of months = m

So,

According to the question;

45 + 10m = 25m

⇒

25m - 10m = 45

15m = 45

m=3

So, After 3 months memberships will cost the same.
