In multiplying fractions, you don't need a common denominator.
3/8 * 6/1 = 18/8
I multiplied the numerator by the other numerator and multiplied the denominator by the other denominator
Now we have to simplify 18/8, the number 2 can go into both numbers
9/4 is the final answer.
Answer:
21
Step-by-step explanation:
BDE and BAC are similar figures
BD/BA = BE/BC
18/(18+36) = a/(a+42)
18/54 = a/(a+42)
1/3 = a/(a+42)
a+42 = 3a
42 = 2a
a = 42/2
a = 21

Step-by-step explanation:
so 1/3 of the area of the park is for a playground.....and 1/4 of the area of the playground is for swings

If you need to find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Square the length of the 2 sides, called a and b, then add them together. Take the square root of the result to get the hypotenuse
