Answer:
1.504 x 100 = 150.4
Step-by-step explanation:
By multiplying the number by 100, we are moving the decimal two places to the right, which will make 0 in the one's place.
1.504
^ Here, 1 is in the one's place
150.4
^ Here, 0 is in the one's place
(Hint, the one's place is right in front of the decimal point)
