Who ate more candy bar if both boys ate half?

Manny ate half of a 7" long, 1/8"thick candy bar. Danny ate half of a 4" long,1"thick candy bar. Who ate more? And why? or:Manny ate half of a 7\" l

Manny ate half of a 7" long, 1/8"thick candy bar. Danny ate half of a 4" long,1"thick candy bar. Who ate more? And why?

or:Manny ate half of a 7\" long, 1/8\"thick candy bar. Danny ate half of a 4\" long,1\"thick candy bar. Who ate more? And why?


or:Well, let's get one thing straight from the start: this is a volume problem, but when you discuss food you measure weight, not volume.Get a ruler in your hands. Measure things until you start to understand how a ruler works. Measure some stuff and figure out where the center is. Say you measure a book and it's 7/8\" thick. You look at your ruler and see that every eighth is divided into two sixteenths, so obviously half of 7/8\" is going to be 7/16\". If you write that out you have 1/2 x 7/8 = 7/16. And you notice that 1/2 is divided into 2/4 and then into 4/8 and so on, so you can convert anything to anything by multiplying all the numbers on top and then all the numbers on bottom.Other rulers are divided into 10 and 100 parts. But an inch is still an inch, so anything on one ruler can be translated to the other ruler. A half inch on one ruler is 5/10 or 50/100 on the other. An eighth inch is just 12.5 marks when you have 100 marks per inch. A metric ruler divides an inch into 25.4 parts, so a half inch would be 12.7 of those parts. Pretty simple, isn't it? Practice this a bit and people will think you went to wizard school.Volume is height times length times width. You are not given width, so there is no answer. We could assume that the candy bars were the same width, but a math problem is a lousy place to leave things to somebody's guessing or assuming. Mistrakes kill people.
