Answer:
He scored a 4/10, 40%, .40
Step-by-step explanation:
4 out of 10 tells you what the fraction is. You might need to also list 40/100 just to be safe.
to make a fraction a parcentage you turn the fraction into a part of 100 and then take the top half and put a parcent symbol behind it, hence 40%.
to make a parcentage a decamle you move the decamle point two places to the left, making .40 or .4
