Mrs. Williams teaches preschool. At snack time on Monday, Mrs. Williams used 2/3 of a bottle of juice to give 12 students each an equal amount of juice. On Tuesday Mrs. Williams gave juice to 21 students.

Respuesta :

Answer: 1 1/6

Step-by-step explanation:

Let the amount of students that a bottle of juice can cater for be x. Therefore,

2/3 × x = 12

2x/3= 12

2x = 12 × 3

2x = 36

x = 36/2

x = 18

Since Mrs. Williams gave juice to 21 students, the number of bottles of juice that was used will be:

= 21/18

= 1 3/18

= 1 1/6
