What is the lest common multiple of 14 and 21?

Answers

Answer 1
Answer: 42.

There's a trick to finding this easily. Take the prime factors of both numbers.

14 = 7 × 2
21 = 7 × 3

Now, multiply the unlike numbers.

2 × 3 = 6

Multiply the 6 by one of the like numbers.

6 × 7 = 42.

That's it. Hope this helps!
Answer 2
Answer: Least common multiple is the smallest number is a multiple of both numbers. First the numbers should be factored into its primes.
14 = 7 X 2
21 = 7 X 3
The least common multiple will be 7 X 2 X 3 = 42

What is the square root of 102 approximated to the nearest tenth

Answers

The requried square root of 102, approximated to the nearest tenth, is approximately 10.1.

To approximate the square root of 102 to the nearest tenth, you can use a calculator or perform the calculation manually. Here's the manual method:

Start by guessing the square root. The square root of 100 is 10, so it's a good starting point.

Divide 102 by the guessed value (10) to get a new approximation.

102 / 10 = 10.2

Take the average of the guessed value and the new approximation.

(10 + 10.2) / 2 = 10.1

Repeat steps 2 and 3 using the new approximation to get a more accurate result:

102 / 10.1 ≈ 10.099

(10.1 + 10.099) / 2 ≈ 10.0995

So, the squareroot of 102, approximated to the nearest tenth, is approximately 10.1.

how can changing improper fractions to mixed numbers help me determine between which two whole numbers a fraction lies

Answers

Answer:

By indicating, through the whole number of the mixed fraction,  the lower boundary  in which the fraction lies.  

Step-by-step explanation:

Improper fractions can be expressed as mixed numbers by performing a división of numerator by denominator and expressing the remainder as fraction. Example 6/4  is equal to 1 2/4 or 1.5 that is the number of times 6 can be divided by 4 and the remainder of two expressed as a fraction. The whole number of the mixed number is the lower boundary whole number of 6/4. The upper boundary is this whole number + 1 , in this case 1+1 = 2 . So, by using the mixed fraction we can see that 6/4 is between 1 and 2.  

So for example 4/2 is a improper fraction. First think how many times can two go into 4 and that is 2 so the answer is two. Let's try 7/4. 4 can go into 7 one time but there is some reminders so u take the remainder and use it as the numerator. Then u keep the same denominator and so the answer is 1 3/4

Mrs. Martin wants to place a ribbon around the outer edge of a rectangular mirror. The area of the mirror is 324 square inches. The width is of the mirror is 12 inches. How many inches of ribbon does Mrs. Martin need?

Answers

The inches of ribbon that Mrs. Martin needs will be equal to the perimeter of the rectangular mirror.

We know that the area of a rectangle equals the length times the width.

Area = length * width
324 square inches = length * 12 inches
length = 27 inches

The perimeter of a rectangle is two times the length plus two times the width.

Perimeter = length + length + width + width
Perimeter = 27 + 27 + 12 + 12 
Perimeter = 54 + 24 
Perimeter = 78 inches

Therefore, Mrs. Martin needs 78 inches of ribbon.

The price of a computer set is Rs 5200 less than the price of the TV set. If the total price of a set of computer and a set of TV is Rs 105200, find the price of each.​

Answers

Answer:

Step-by-step explanation:

Let the Price of TV set be  x.

The price of computer = x - 5200

x + x - 5200 =  105200

2x = 105200 + 5200

2x = 110400

x = 110400/2

x = Rs. 55200

Price of TV set = Rs. 55200

Price of computer set = 55200 - 5200 = Rs. 50000
