How to do HCF and LCM

Answer:

8, 2, 8, 2

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

9, 1, 9, 1

2, 8, 2, 8

3, 7, 3, 7

6, 4, 6, 4

Step-by-step explanation:

you would have to have the numbers repeat so it works, for instance, you could do 9,1,9,1 as the first row then 2,8,2,8 as the second row and for the third row you could do 3,7,3,7 and for the fourth row you could do 6,4,6,4 so both the columns and rows add to 20

The mixed number will be of form 5 37/100 .

Given,

Decimal number = 5.37

Here,

To turn a decimal into a mixed number we write the number in front of the decimal point.

We look at the numerator and the denominator and make the decimal a mixed number.

In this case, we have the number 5.37 .

Thus first convert the number into simple fraction,

Divide the number by 100.

Fraction form = 537/100

Now,

To convert the number into mixed form,

separate the whole number and decimal form to get the mixed number .

Whole number = 5

Decimal number = 0.37

Mixed form = 5 37/100
