$450$ $450$ grams

Let the unknown amount be $x$ $x$ .

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

Write this as a proportion..

$\frac{243}{x} = \frac{54}{100}$ $243/x= 54/100$

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

$x = \frac{243 \times 100}{54}$ $x = (243 xx100)/54$

$x = 450$ $x = 450$ grams

You can also think of this as a ratio:

Increase 243 in the ratio $100 : 54$ $100 : 54$

$243 \times \frac{100}{54}$ $243 xx 100/54$

= $450$ $450$ grams
