There is a total of 270 men, women and children on a train. the ratio of men to women is 4 : 5. the ratio of women to children is 10 : 9. how many men are on the train?

Because the ratio of women to children is 10:1, double the ratio of men to women so the women are both 10:

Men to women becomes 8:10

Now total the 3 ratios: 8 for men, 10, for women and 9 for children:

8 + 10 + 9 = 27

Divide total people by that number:

270/27 = 10

Multiply 10 by each ratio:

Men = 8 * 10 = 80

Women = 10 * 10 = 100

Children = 9 *10 = 90

There is 80 men.

A 12

Step-by-step explanation:

the total amount of boys on the chart are 35 and 23 are already marked on the super slide, so that means that there are 12 people marked as the Ferris wheel because 35-23=12
