Question

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

 

I would like to know how to solve this question. 

 

Thank you

Answer 1

Weight w

w₀ = original weight

w = worked out weight

 

w=(88%)w₀ = 0.88 w₀

1.1 = 0.88 w₀  dividing both sides by 0.88

1.1/0.88 = 1.25 original weight

Answer 2

1.25kg  Here is how.  If a loaf of bread loses 12% of its weight when baked, a baked loaf bread is 88% of it's original weight (100-12).  Remember % means divided by 100 therefore 88/100 equals 1.1/?  cross multiply and you get 1/25kg.
