If there are 245 total preschoolers, there will be 105 boys.
- What is unitary method?
- The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. What can be values and units.
- Let's say you go to the store to buy six apples. You are informed by the shopkeeper that he is offering 10 apples for Rs 100. In this instance, the value and the units are the price of the apples.
- Recognizing the units and values is crucial when using the unitary technique to a problem.
- Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things. We are aware of the quantity of apples and the amount of money in the aforesaid problem.
acc to our question-
- Fraction of boys = 3/7
- Fraction of girls = 4/7
- Total number of students = 245
- The number of boys will be:
- = 3/7 × 245.
- = 105 boys
Therefore, there are 105 boys in the school.

Answer:

Step-by-step explanation:
We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.
For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.
Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.
What times 5 equals 10?
2
Now multiply both numerator and denominator by 2 to get our portion.


Now we have the same denominator, let's add our two fractions and see how much we have left.
8/10 + 1/10
9/10
We have 1/10 missing, therefore 1/10 is the answer.
7) 8.9
8) 6.7
9) 12.2
10) 7.6
11) 7.3
12) 6.3
Answer:

Step-by-step explanation:
37=11+(37-1)*8
37 is the term you want
11 is the first term from least to greatest
(37-1) is from the term you want minus 1
*8 because 8 is the difference between each term
