Claire is making a loaf of bread. A loaf of bread loses 12% of its weight when it is baked. Claire wants the baked loaf of bread to weigh 1.1 kg. Work out the weight of the loaf of bread before it is baked.

Answer

To find the weight of the loaf of bread before it is baked, we can set up an equation based on the information given. 1. Let the weight of the loaf before baking be represented as \( x \). 2. When the loaf is baked, it loses 12% of its weight, which means it retains 88% of its original weight. - This is calculated as: \( 100\% - 12\% = 88\% \) or in decimal form, \( 0.88 \). 3. According to the problem, after baking, the loaf weighs 1.1 kg. Therefore, we can express this relationship mathematically as: \[ 0.88x = 1.1 \] 4. To find \( x \), we will divide both sides of the equation by 0.88: \[ x = \frac{1.1}{0.88} \] 5. Now perform the division: \[ x \approx 1.25 \] 6. Thus, the weight of the loaf of bread before it is baked is approximately 1.25 kg. In conclusion, the weight of the loaf of bread before it is baked is approximately 1.25 kg.
