Show work when multiplying 3.9×5.3
3.9 x 5.3 = 20.67 im not really sure how i would show my work while typing, but if you really need to see it i could insert a picture, let me know.
I use the expansion distributive thingremember a(b+c)=ab+ac3.9=4-0.13.9 times 5.3=(4-0.1) times 5.3=5.3(4-0.1)=5.3(4)+5.3(-0.1)=(5+0.3)4+5.3(-0.1)=20+1.2-0.52=20+0.68=20.68taht's one way
