When you multiply fractions does the denominator change
Ede4ka [16]

Answer:

Step-by-step explanation:

When multiplying fractions, simply multiply the numerators together and then multiply the denominators together.

This works whether the denominators are the same or not.

(e.g) if you multiply the fractions 3/2 and 4/3 together, you get 12/6.

hope this explanation helped..<3

general admission tickets to the fair cost $3.50 per person ride passes cost an additional $5.50 per person parking called 6 for
pantera1 [17]
To solve this, you must define the variable first.
You can usually choose the variable to be what we are asked to find.

Let the number of people in the family be x.

The amount paid by each person (x) for admission and ride passes was $3.50+$5.50=$9.00

Only one payment for parking ($6) was made by the family.

The total amount spent was $9×x+$6
The total amount spent was $51.

Therefore, 5 people in the family went to the fair.
