#450# grams

Explanation:

Let the unknown amount be #x#.

#243 "g of some amount " = 54%#

Write this as a proportion..

#243/x= 54/100#

If 243 grams is 54%, then how many grams is 100%?

#x = (243 xx100)/54#

#x = 450# grams

You can also think of this as a ratio:

Increase 243 in the ratio #100 : 54#

#243 xx 100/54#

=#450# grams
