Step-by-step explanation:
Given
Yellow = 40 beads
Red = 64 beads
Required
Highest number of bracelets
To answer this question, we simply need to determine the highest common factor of the given parameters.
40 = 2³ * 5
64 = 2⁶
HCF = 2³
HCF = 2 * 2 * 2
HCF = 8
Hence, the maximum number of bracelets is 8

Answer:
There are 84 total boats.
Step-by-step explanation:
In order to find this, we first need to find the fraction which are red. We can do this by multiplying the whole by how many are not white.
1 * 1/4 = 1/4
Now we take that amount and multiply it by the amount that are not blue of the remaining.
1/4 * 3/7 = 3/28
Now that we have this, and we know this is 9 boats, we can divide 9 by this fraction and it will give us the total number of boats.
9 ÷ 3/28 = 84
