The answer would be 1,000
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
The answer is 20, since if you set up the equation
x+80=3x
Move the x to the right by subtraction
80=4x
Divide by 4
x=20
Im not sure but i think it is 15 - x
5:3 20:12 just multiply by whatever number by both of them
