Tasya [4]
Here in this case the answer is "a". The way to find the percentage is to add all the numbers you have which is $49. And then you need to use it to divide it with the percentage you need for the number. Which in this case you are searching for shoelaces and it $4. So you divide the cose of the shoelaces $4  to the total amount $49. And then you multiply by 100 to get the percentage. If you round it off the the tenth place you should get 8.2%

There were 63 equal piles of plantain fruit put together and 7 single fruits. They were divided evenly among 23 travelers. What
antiseptic1488 [7]

Answer:

There are 28 fruits in each pile.

Step-by-step explanation:

We are given the following in the question:

Let x denote the number of fruits in each pile and y denote the number of fruits that every traveler receive.

Consider the diophantine equation:

63x + 7 = 23y\\63x-23y = -7

We obtain the greatest common divisor of (63,-23).

The greatest common divisor f 63 and -23 is 1.

Therefore, there exist \alpha,\beta such that

-23\alpha+63\beta=1

By applying extended Euclidean Algorithm, we have,

1 = (1\times 6)+(-1\times 5)\\1 = (1\times 17)+(3\times 6)\\1 = (3\times 23)+(-4\times 17)\\1 = (-4\times 40)+(7\times 23)\\1 = (7\times 63)+(-11\times 40)\\1 = (-11\times -23)+(-4\times 63)

1 = (-11\times -23) + (-4\times 63)

Multiplying -7 on both sides, we get,

-7 = (77\times -23) + 28\times 63)

Thus, we get,

x = 28\\y=77

Thus, there are 28 fruits in each pile.
