1 / 4 =Always take 4 multi. something in decimals.Take 4 x 0.1 = 0.4 so we need 0.6 to get 1 Take another 4 x 0.1 = 0.4Now we have 0.4 + 0.4 = 0.8 , so we need 0.2 to get 1Also take 4 x 0.0.5 = 0.2 ===> Now we have 1 because (0.4 + 0.4 + 0.05=1)Finally, The result equal addition of the underlined decmiles (chunking)which mean :0.1 + 0.1 + 0.05 = 0.251 / 4 = 0.25 in decimals:) BY SAILOR

Chunking is a mental strategy used in maths to make certain kinds of problems easier. Instead of adding 76 +34 ------- Let's see, 6 + 4 is ten, so write the zero down, then carry the one, then 7+3 is ten, but add the one that's 11, so write down 1, and then carry the one, and then write down the one. You get the correct answer, 110, but there is a simpler way to do it. Think 70+30 = 100 ; 6+4 = 10 ; 100+10 = 110 It also works with subtraction 110 -97 ----- Think 100 - 90 leaves 10 10-7 leaves 3 add what is left: 10+3=13

If the two numbers are written as ab and cd then these represent the decimal numbers (10a + b) and (10c + d) and their product is 100*a*c + 10*a*d + 10*b*c + c*d = 100*a*c + 10*(a*d + b*c) + c*d. This is the result that you would get if you used partial products (also called chunking).
