For every 8 red pens on the teachers desk there are 12 pencils. if she has 60 writing implements, does she have enough red pens for 60 kids? explain

No she does not

Step-by-step explanation:

8pens + 12pecils= 20writing inplements

20+8+12=40

20+8+12=60

You needed 3 sets of 8 pens and 3 sets of 12 pencils to get 60.

3*8=24

24 is less than 60, so she does not have enough pens for 60 students
