Atypical person has 100 000 strands of hair on their head. suppose each strand is 50 cm long. how many kilometres of scalpal hair would the typical person have?

50km

Step-by-step explanation:

This is because 1,000,000 strands times 50cm is 5,000,000cm. 5,000,000cm is 50 km.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
