We know the number of all ways to take one marble and then take another marble is: 10x9=90
The first time, Jamie wants to pick a white and the ways is: 3
Now we have only 9 marble with 2 white and 7 blues, she has 7 ways to take a blue . So, she has 3x7=21 ways to take what she wants.
And we do the division 21:90=7/30. and that is the answer
In order to check whether its greater than or less than, First You have to make denominator value equal of both ratio value. then we have to make denominator value equal i.e. After that you check which ratio Numerator value is greater.
Answer:
3 vegetable trays, 2 sandwich trays
Step-by-step explanation:
I'm not quite sure what we're supposed to find, but if we were to find how many of each we can buy with $120 it would be 3 vegetable trays and 2 sandwich trays.
20 + 20 + 20 = $60
30 + 30 = $60
60 + 60 = $120
8*30 = 240
And after you divide it by 3 is 80.
M = 80 final answer
