I need help with multiplying decimals i ust dont get it i also need help with dividing decimals

Step-by-step explanation:

Okay, first multiplying decimals:

If you want to multiply decimals first you have to put the 2 decimals one on top of each other

for example:

  2.27

x 4.89

Then multiply it just like if you were multiplying a regular number without the decimals

  227

x 489

This equals 111,003 now to figure out the answer we can count that there are 4 numbers after the decimal point so you move the decimal point 4 to the left so the answer would be 11.1003

you cant answer this dummy

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
