41.2 x 1.5. Then explain where the decimal point should go and why
Vinil7 [7]

Answer:

This is really simple, here i'll explain:

Step-by-step explanation:

41.2 x 1.5=

count how many spaces are after the decimal point.

for example, 41.2 has 1 space after the decimal point. The decimal 1.5 also has 1 space after the decimal point. So if you add the spaces it would be 2 because 1 + 1 = 2

After that, take away the decimal point, and just multiply like you normally would.

412 times 15

this would be 6180

after you do the multiplication, you will add the decimal point.

The decimal point will go in between 1 and 8 because there were 2 spaces after the decimal point in the numbers, and if you add them it would be 2 spaces.

Hope this helps!
