Answer:
- 1/4
- 3/5
Step-by-step explanation:
You find the part by expressing the ratio as a fraction, then simplifying.
1. 5/20 = (1·5)/(4·5) = (1/4)·(5/5) = 1/4
5 is 1/4 of 20.
__
2. 12/20 = (3·4)/(5·4) = (3/5)·(4/4) = 3/5
12 is 3/5 of 20.
Answer:
1.2-0.8
Step-by-step explanation:
Add 0.4 and 0.8
Answer:
Y= 15
x = 12
Step-by-step explanation:
Okay, so the sides that are across from eachother, are always equal to eachother, in a parallelogram.
So, 5y-20 = 2y + 25
Next, you add 20 to both sides, and then subtract 2 from the right side, and subtract 2 from the left side ,and you get 3y = 45
divide 45 by 3 , and you get 15.
DO the same thing for the X's.
Let 6x represent the men
5x represents the women
The ratio of men to women is 6 to 5 or 6/5
6x / 5x = 1500/ W where W is the number of women
6/5 = 1500/W
W = 1250 women
