Six donkeys are each given two 5ml spoon of medicine three times each day. calculate the number of whole days a 2 litre bottle will last.

the answer is 11 but how?

2 liters of bottle will last for 11 days

Solution:

Given that six donkeys are each given two 5 ml spoon of medicine three times each day

To find: number of days 2 liter bottle will last

From given question,

six donkeys are each given two 5 ml spoon

Therefore, six donkeys are each given 10 ml spoon of medicine ( since two 5 ml = 2 x 5 = 10 ml)

six donkeys each given 10 ml

Therefore, one donkey = 10 ml

For 6 donkeys,

6 donkey = 6 x 10 ml = 60 ml

Therefore, for 6 donkeys, they give 60 ml medicine three times a day

one time = 60 ml

three times a day = 3 x 60 ml = 180 ml

Thus for one day, 6 donkeys are given 180 ml of medicine

Let us convert 180 ml to liter

We know that,

1 liter = 1000 milliliter

Therefore,

Now to find the number of whole days a 2 litre bottle will last:

Let "x" be the number of days 2 liter bottle will last

For one day, 6 donkeys are given 0.18 liter of medicine

1 day = 0.18 liter

"x" days = 2 liter

This forms a proportion

By cross multiplication, we get

Thus 2 liters of bottle will last for 11 days

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
