Write a rule that tell how to use mental math to find the product 30,000 x 50,000​

Step 1. Think of the basic fact. Multiply. 6  2  12

Step 2- Count the number of zeros in the factors.

                60 has 1 zero and

                     20 has 1 zero.

Step 3- Write that number of zeros to the right of The answer is 1,200.

the basic-fact product.

Step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
