Note that
Find the grearest common factor GCF(30,42). You can see that numbers 30 and 42 have common factors 2 and 3, then
This gives that the greatest number of identical vases florist can fill is 6. Each vase will contain
carnations;
roses.
Therefore, in each vase will be 12 flowers (5 carnations and 7 roses).
A rectangular prism is defined by three lengths.
We can find out how many unit cubes would be in a prism by multiplying these three lengths together--that's how we find our <em>volume</em>.
Similarly, we can come up with different ways to multiply together three different numbers and make 18.
Each combination would be a new rectangular prism, with one catch:
Order doesn't matter. A prism with lengths 2, 2, and 3 is the same as one with lengths 2, 3, and 2, so don't make that mistake.
To find each combination, keep splitting 18 in different ways.
If one of the ways we split it can also be split, we need to write out that, too.
Here are the possible combinations:
18 × 1 × 1, obviously
9 × 2 × 1. splitting off 2
6 × 3 × 1. splitting off 3
4 × 6 × 1. our next biggest we can take out is 6, which can also be split...
4 × 3 × 2. there's the split of 6 into 2 and 3
<em>(3 × 6 × 1 is a repeat.)</em>
3 × 3 × 2 is new, though
<em>(2 × 9 × 1 is a repeat...)
</em><em>(2 × 3 × 3 is a repeat...)
</em>(aaaand 1 × 1 × 18 is a repeat. let's count up our combinations.)
<em>
</em>
There are 6 possible ways to multiply numbers together and get 18...
So 6 possible rectangular prisms.
Answer:
The rate is 13. Which also means for every tree there are 13 apples
Simple division☺ You divide the top by the bottom. 26 apples divided by two tree trees is 13 apples per tree. 39 apples divided by three trees is 13 apples per tree. See? There is a pattern. 130 apples divided by 10 trees is once again 13 apples per tree
