Answer:
54 as a percentage of 216% is 116.64.
Step-by-step explanation:
100% of 54 is 54 so 54 x 2 would be 108. We have solved 200% of it now for the 16%. The percentage of 54 of 16% would be 8.64. Now add up all we have learned.
108 + 8.64 = 116.64
It would be 60cm because 40 plus 20 equals 60
82% of 503 is 412.46 hope this helps
