Answer:
4
Step-by-step explanation:
We are given that 28 girls and 32 boys volunteer to plant at a school.
The principle divided the girls and boys into identical groups that have girls and boys in each group.
We have to find that how much the principle can make greatest number of groups.
We will find HCF of 28 and 32
[tex]28=2\times 2\times 7[/tex]
[tex]32=2\times 2\times 2\times 2\times 2[/tex]
Highest common factor of 28 and 32 =[tex]2\times 2=4[/tex]
Therefore, the principle can makes 4 groups with 7 girls and 8 boys.
Hence,the greatest number of groups is 4 can made by principle.
