Answer:
1.05 (only enter in one box)
Explanation:
5*3 = 15, carry the one over and (3*3) + 1 = 10, carry the one over and (0*3) + 1 = 1. Therefore the final answer is 1.05 and since it is a single digit being multiplied there is nothing being added for the second box, so just place 0. 1.05 + 0 = 1.05.
I hope this helps!! :)
