Question 4. How much is it:
The) from 6?
B) in ?
w) from 12?
Question 5. There are a total of 150 vegetables in a stall. Of these, one-third are potatoes and one-fifth are carrots. Reply:
a) How many potatoes are in the bank?
b) How many carrots are there in the bank?
c) Are there any other types of vegetables on the stand?
Question 6. What is one-sixth of two-thirds of 240?
Question 7. In a parking lot for cars and motorcycles there are 49 vehicles, of which two sevenths are motorcycles. How many cars are there in the parking lot?
Question 8. Using fractions express the following quantities:
a) half of half
b) half of half of half
c) twice as many as two sevenths
Question 9. How many minutes corresponds in of time?
Question 10. How many days corresponds in a month?
The)
B)
w)
The)
Like 7. 3 = 21, so x = 3.
B)
Like 2. 8 = 16, so x = 8.
w)
Like 1. 6 = 6, so x = 1.
The)
B)
w)
The) from 6?
Therefore, of 6 is equal to 2.
B) in ?
Therefore, in it's the same as .
w) from 12?
Therefore, of 12 equals 9.
a) There are a third of potatoes, so we must calculate out of 150:
So there are 50 potatoes in the bank.
b) There are one fifth of carrots, so we must calculate out of 150:
So there are 30 carrots in the bank.
c) Subtracting the number of potatoes and carrots from the total number of vegetables, we can see that there is another type of vegetable:
150 – 50 – 30 = 70
That is, there are 70 units of other vegetable(s).
We want to know how much in out of 240:
Therefore, in of 240 is .
We need to know how much of 49:
So there are 14 motorcycles in the parking lot.
49 – 14 = 35
So there are 35 cars in the lot.
a) half of half is the same as in :
b) half of half of half is the same as in in :
c) the double of two sevenths is the same as 2 of :
How many minutes corresponds in of time?
One hour equals 60 minutes, so we must calculate in from 60:
Therefore, it corresponds to 18 minutes.
How many days corresponds in a month?
Considering a month of 30 days, we must calculate in from 30:
Therefore, it corresponds to 15 days.
