What steps do i need to do to get 18×8.723×56.1and47×5.92

For 18 x 8.7 = 156.6

For 23 x 56.1 = 1290.3

For 47 x 5.92 = 278.24

but i don't know how to explain the steps, just the answers.
but hope i helped.

When you multiply decimals with whole numbers you have to line them up so example 
18.0
x8.7 that will equal 156.6

23.0 times 
56.1 equals 1,290.3

47.00 times 
  5.92 equals 278.24

Most of the people don’t make the sense of taking it
