Step-by-step explanation:
Remember 'of' in this sentence means times(*). % shows a certain number/100.
a1) 48% 'of' what number is 60?

i.e. a should be a finite real number.
Step-by-step explanation:
previous =£400
present=£504
percentage=(£504-£400)/£504*100

To answer the question above, use conversion factors and dimensional analysis. In this given, it is easier to use grams as the basis.
a. (2 centrigrams) x (1 gram / 100 centigrams) = 0.02 grams
b. 2 grams
c. (2 hectograms) x (1 gram / 0.01 hectogram) = 200 grams
d. (2 kilograms) x (1 gram / 0.001 kilogram) = 2000 grams
e. (2 milligrams) x (1 gram / 1000 millimeters) = 0.002 grams
Thus, the answer is 2 milligrams.
