Find the part using the multiplication shortcut. 52.5% of 2080 trucks ( type a whole number or decimal)

OpenStudy (anonymous):

im confused with this

OpenStudy (anonymous):

when you want to find a certain percent of something, you move the decimal two places to the left and multiply

OpenStudy (anonymous):

0.525 x 2080

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

=1092

OpenStudy (anonymous):

yep

OpenStudy (anonymous):

would that be the answer or do i change it too a decimal

OpenStudy (anonymous):

it says type a whole number or a decimal

OpenStudy (anonymous):

1092 doesnt need a decimal

OpenStudy (anonymous):

it is a whole number which is ok

OpenStudy (anonymous):

its a whole number

OpenStudy (anonymous):

if you wanted to show 1092 with a decimal you could write 1092.00, but that is unnecessary because it is already whole

OpenStudy (anonymous):

Ok. I get it. Thanks. Can you help me with another problem please

OpenStudy (anonymous):

yes
