# Proportion word problem: hot dogs

Mika can eat 21 hot dogs in 66 minutes. She wants to know how many minutes it would take her to eat 35 hot dogs if she can keep up the same pace.

• Can't you just cross multiply?
• You Could! Our job is to show the most efficient way so that students know how to do it efficiently on their own!
• how do you solve a poportion?
• Couldn't you first divide 66/21 and then multiply that number by 35?

• I am confused why Sal multiplies by the fraction in the equation instead of dividing by this.

(21/66)/(21/66)m = 35/(21/66) is the same as (66/21)*(21/66)m = 35*(66/21)?

In the first equation the fraction is dividing, in the second equation it is multiplying.

How many minutes would Mika need to eat 35 hot dogs?
• Who eats THAT much hot dogs? :/
And also wouldn't that make your stomach hurt?
I can only survive by eating 1 or 2 hot dogs...
And it looks like that Mika in this math problem is gonna have a ride to the hospital + some surgery.
