What are two numbers that equal 100?
1 × 100 = 100. 2 × 50 = 100. 4 × 25 = 100. 5 × 20 = 100.
What are the number Bonds of 100?
28 and 72 are number bond pairs that add to make 100.
What is the sum of 100?
Therefore, the sum of first 100 natural numbers = 5050.
What are all the factors of 100?
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
What is the common factor of 100?
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50 and 100.
How do you calculate number bonds?
So for example to find the number bond to 100 of 36, you first add 4 to reach 40, then add 60 to reach 100. So the number bond to 100 of 36 is 64.
How do you find the sum of the first 100 numbers?
Now using the formula of sum given below: S100=n2[2a+(n−1)d]substituting the values. we getS100=1002[2×1+(100−1)×1]S100=50[2+99]S100=50×101S100=5050∴ The sum of first 100 natural numbers is 5050.
How do you find a pair of numbers whose sum is 100?
Among all pairs of numbers whose sum is 100, how do you find a pair whose product is as large as possible. (Hint: express the product as a function of x)? Suppose two numbers sum to equal 100. Let x represent the first number. Then the second number must be 100 − x, and their product must be x(100 −x) = −x2 + 100x.
Which number pairs with 64 add to make 100?
28 and 72 are number bond pairs that add to make 100. To find a number bond to 100, first add on to the next multiple of 10 and then add on the required multiple of 10 to get to 100. In this number bond example, we are asked which number pairs with 64 to make 100.
How to find the product of two numbers that sum to 100?
Suppose two numbers sum to equal 100. Let x represent the first number. Then the second number must be 100 − x, and their product must be x(100 −x) = −x2 + 100x.
What number bond pairs with 64 to make 100?
From 70, we need to add 30 more to make 100. Our number bond that pairs with 64 to make one hundred is 36. What are Number Bonds to 100? Number Bonds to 100 are pairs of numbers that add together to make 100.
