Sari has 3 times as many pencil erasers as Sam. Together, they have 28 erasers. How many erasers does Sari have?

Asked by patriciansingh

Answer (3)

To solve this problem we can use equation. If we say that x is number of Sams pencils we can say too that Sari has 3x (because she has 3 times more) And we know that together they has 28 pencils. x+3x=28 4x=28 /:4 (divide both sides by 4) x=7 Sam has 7 pencils. We know that Sari has 3 times more so 7*3=21 -its the result.

Sari has 21 erasers, since Sam has 7 erasers and Sari has 3 times the number Sam has. Together, they total 28 erasers. Therefore, Sari's erasers can be calculated as 3 times 7, which equals 21.
