322/14 = 23
322 / 14
14 cannot go into 3, so 14 can go into 32 twice,
32-28 = 4 drop the 2
42. 14 can go into 42 3 times
42-42 = 0
Your answer is 23
Answer:
10 kg
Step-by-step explanation:
In 3% concentration of 20 kg of seawater, there will be
kg of salt.
So, if it is a 2% solution of seawater,
Then 2 kg salt will be there in 100 kg solution.
So, 0.6 kg salt will be there in
kg of solution.
So, to make a solution from 3% to 2% we have to add (30 - 20) = 10 kg of water with a 20 kg solution. (Answer)
Answer:
1/20
Step-by-step explanation:
Karina ate 1/2 of the muffins. Ulysses ate 1/4 of the muffins. Zawanna ate 1/5 of the muffins. Juan ate the rest of the muffins. What fraction of the muffins did Juan eat?
Let the total number of muffins = 1
Hence:
The fraction of muffins Juan ate =
1 - (1/2 + 1/4 + 1/5)
Lowest common denominator is 20
1 - ( 10 + 5 + 4/20)
1 - 19/20
= 1/20
The Fraction of muffins Juan ate is 1/20
Step 1- turn mixed number into improper fraction.
step 2- multiply 3/2 by 3/1
step 3- turn improper fraction into mixed number
And your done! :)
