im trying to help my husband with his math homewok:?

Question

how do i do these problems and show the work:
multiply the following numbers by moving the decimal:
1. 0.08 x 10=
2. 5.65 x 100=

Answer 1

Multiplying by 10 is the same as moving the decimal place some number of places to the right:

1. 0.08 x 10 = 0.8
2 5.65 x 100 = 565

Answer 2

you move the decimals to the right by as many zeros there are in the multiplying number.

1. 0.08 x 10 = 0.8 (move the decimal to the right one place)
2. 5.65 x 100 = 565 (move the decimal to the right two places)

Answer 3

1. 0.08 x 10= 0.8, move the decimal to the right by one place.
2. 5.65 x 100=565, move the decimal to the right by two places.

Answer 4

10^1 - move decimal point 1 place to the right
10^2-move decimal point 2 places to the right


10^-1 = move decimal point to the left one place
10^-2 = move decimal point to the left two places.

remember, the general rule for multiplying decimals

multiply all number ignoring the decimal point, multiply as if they are regular numbers.
In the answer - add up the total number of decimal places in all numbers multiplied and starting from the furthest righ position, move the decimal point this many places in the answer.

.085 X 10 =0850 (place decimal point three units from the right)
.85

Answer 5

Is your husband ten years old?

Just kidding!

1) Move the decimal over one space since there's one 0 in 10. The answer is 0.8

2) Move the decimal over two spaces since there's two 0's in 100. The answer is 565

Answer 6

0.08 x 10=0.8

5.65 x 100=565

Answer 7

u juz show how you move the decimals or write out the words: ....then i moved the decimals points over 2 places

Answer 8
