Question

Johanna has a very accurate scale, Last month, she weighed 133.46 Ibs, This month, she weighs 177.67 Ibs. How much did she lose?

Answer 1

the way your question is worded she did not lose any weight. she actually gained 44.21 lbs.

(if you meant 177.67 last month and 133.46 this month, then she would have lost 44.21 lbs.)
