i know for 4 (10.2) i do this

= 4 (10 + 2)

= 4 (10) + 4 (2)

= 40. + .8

= 40.8

but I am not sure how to show work on on following 2 problems:

11.6 (9)

and 3.4 (5)

#2 (3*0.4)+(3*0.5)

Figure out the rest!

**MARKO**, Monday, September 26, 2011 at 7:39pminstructions are to find the product mentally using the distribution property:

11.6 (9) = 104.40

but you have:

(11 x 0.6) + (11x5)

6.6 + 55

= 61.60 ?? i dont understand

problem 2

3.4 (5)

you show: 3 x 0.4 + 3 + 0.5

= 1.2 + 15 = 2.7? i dont understand?

pls explain how you got this
