Answer: There are 5 pins which is the greatest number of pins that he can put in each prize.
Step-by-step explanation:
Since we have given that
Number of square pins = 15
Number of round pins = 20
We need to find the greatest number of pins Jerome can put in each prize.
According to question, Every prize will have one kind of pin. Each prize will have the same number of pins.
So, H.C.F. of 15 and 20 = 5
Hence, there are 5 pins which is the greatest number of pins that he can put in each prize.
