She has 4 groups all together. 3 groups with ten rocks each and 1 group with 8 rocks(8/10).
Answer:
72 in 150 seconds.
12/25=0.48
0.48 per second (not full baskets note)
.48x150= 72 baskets
You multiply 14.99 by 3 then plus 4.99 and it gives you 49.96 dollars
Stop copying the question, it's confusing
so 100 cookies and 20 brownies
what is the greatest number you can divide them both by?
find the GCF
factor them
100=2*2*5*5
20=2*2*5
so the GCF is the common group to both or 2*2*5 or 20
100/20=5
20/20=1
there are 20 groups, each wit 5 cookies and 1 brownie
20 groups
