Question

The weight of 10 identical samples of a substance is 0.001 pound what is the weight of 100 samples?

Answer 1

0.01 pound, assuming the 100 samples are also all identical.

Answer 2

so 10things=0.001lb
find 100things
10tings=0.001
10things to 0.001 =100things to y
10t/0.001=100t/y
mulltiply both sides by y
10ty/0.001=100t
multiply both sides by 0.001
10ty=0.1t
divide both sides by 10t
y=0.01lb

the weight of 100 samples is 0.01 lb
