5+8 over 2 ; 6+2 over 2
x=13 over 2 ; Y=4
therefore midpoint=(13/4;4)

Show how to solve 6/15=2/?

Answers

There are two way sof doing this question: 
 1st solution  is : 
 6/15 = 2/5
because 6/15 is divisible by 3 and it is done by this form : 
     3 X 2 = 6
       and
    3 X 5 = 15
2nd solution is:
6/15 = 2/?
here we suppose that the missing value is x:
 6/15 = 2/x 
 you shift the denominators and then  multiply them by the their numerators:
 6 * x = 15 * 2
      6x = 30
 now you divide 6 on both sides:
 6x/6 = 30/6
      x = 5


6 / 15 = 2 / x

6x = 30

x = 30 / 6 = 5

Lattice multiplication

Lattice multiplication, also known as the Italian method, Chinese method, Chinese lattice, gelosia multiplication, sieve multiplication, shabakh, diagonally or Venetian squares, is a method of multiplication that uses a lattice to multiply two multi-digit numbers.To multiply using the box method, first, write each number in expanded form. Then create a box that is the size of the number of digits for each number being multiplied. Next, fill in the box by multiplying the numbers that correspond to each row and column. Finally, all of the numbers inside the box to get the final answer.

Answer: Sorry if my english is bad

Step-by-step explanation: Line up the numbers on top of each other. It will be much easier. Also, if you have two digit numbers, multiply the first column and then the second column (same goes for bigger numbers). An easy way to learn your times tables is to start off with adding multiple of the same number. For example, 3+3+3 = 9 and 3 x 3 = 9
