Question

Also,
A community service organization has 4 men and 21 women in its membership. Write the ratio of women to men.

Write 12/23 as a percent

Answer 1

LCF=180

4:21

12/23 = 52%

Answer 2

Least Common Factor is not a regularly used expression in algebra.

Least Common Multiple of 9, 12, and 20 is 180.
They do not have a common factor.

21 women/ 4 men = 5.25 women / man

12/23 = 52.174 %

Answer 3

9 = 3*3
12=3*4
20=4*5
so the least common factor is 3*3*4*5 = 180

if there are 4 men and 21 women, the women to men ratio is 21 to 4

12/23 = 0.5217 = 52.17%

Answer 4

Factors of those numbers:

9: 1,3,9
12: 1,2,3,4,6,12
20: 1,2,4,5,10,20

Ratio: 21:4

12/23 = 53.17391304%

Answer 5

part a: there is no least common factor. but there is a lowest common multiple/ lowest common denominator: 180

part b:21 to 4, 21/4, 21:4 w/e

partc:52.17%

Answer 6

180

1:5.25

(12/23) x 100 :-D

Answer 7

12=1,2.,3,4,6,12,24,36,48,60,72,84,96,108,120,132,144,156
168,180
20=1.2,4,5,10,20,40,60,80,100,120,140,160,180

lcm is 180

ratio is21;4 or 5 1/4 to 1

12/23=52.174%
