Given:
4621.60 x 9.92
Determine the product.
Solution:
In order to determine the product of two values, start first by multiplying each value from the right to the left, we can start at 2 from 9.92 multiplied to 0,6,1,2,6,4, and so on.
(2)(0) = 0
(2)(6) = 12
we take only 2, and add 1 on the next value
(2)(1) = 2 + 1 = 3
(2)(2) = 4
(2)(6) = 12
take only 2 and add 1 on the next value
(2)(4) = 8 + 1 = 9
= 924.320
We moved two decimal places since 2 is 0.02
Do the same with 9.
(9)(0) = 0
(9)(6) =54
take only 4, and add 5 on the next value
(9)(1) = 9+5 = 14
take only 4 and add 1 on the next value
(9)(2) = 18 + 1 = 19
take only 9 and add 1 on the next value
(9)(6) =54 + 1
take only 5 and add 5 on the next value
(9)(4) = 36 + 5 = 41
=4159.44
Do the same for 9
We move to two decimal places since 9 is . 9 and we have a 0 on the decimal point.
Do the same with 9.
(9)(0) = 0
(9)(6) =54
take only 4, and add 5 on the next value
(9)(1) = 9+5 = 14
take only 4 and add 1 on the next value
(9)(2) = 18 + 1 = 19
take only 9 and add 1 on the next value
(9)(6) =54 + 1
take only 5 and add 5 on the next value
(9)(4) = 36 + 5 = 41
=41594.4
We move only 1 decimal place, since 9 is a whole number.
Add the values in descending digits places.
Final answer:
45,846.272
