Question

a waitress fills bowls with soup. she puts 2/3 of a cup of soup in each bowl. how many bowls can she prepare with 40 cups of soup?

Answer 1

Data:

`(2)/(3)\:cup\:of\:soup\longrightarrow\:1\:(each\:bowl)`

`40\:cups\:of\:soup\longrightarrow\:?\:(each\:bowl)`

Solving: (They are proportional measures, the rule of three is made (directly proportional)


`( (2)/(3))/(40) = (1)/(y)`
multiply cross

`(2)/(3)*y = 40*1`

`(2y)/(3) = 40`
multiply cross

`2y = 3*40`

`2y = 120`

`y = (120)/(2)`

`\boxed{\boxed{y =60\:bowls}}\end{array}}\qquad\quad\checkmark`
