The pizza costs £18.00. Mark agrees to pay 1/4 of the cost. Samuel agrees to pay 1/2 of the cost Imran agrees to pay the rest. How much does Imran pay?

4.5 or 4.50 dollars

Step-by-step explanation:

if we split 18.00 into each part of the fraction would be 4.5 . or 4.50

mark pays 4.50

samuel pays 9.00

add those both and you'll get 13.50 $

now subtract 13.50 from 18.00 ( og price)

imran pays 4 . 5 0

hope this helped :p
