You build a model with a scale of 1: 25. your friend builds a model of the same object with a scale of 1: 50. which model is bigger? explain.

Your friends cause the scale factor is greater

Models are normally smaller than the original (if you have a model of a bacteria or a cell, then the model is larger)

if the model is smaller than the real thing

1:25, 1<25
that means that every 1 unit in the model represents 25 units in real life
the model is 1/25 of the real size

1:50
1 unit represents 50 units in the real size
1/50 of the real zie

1/25>1/50 since
2/50>1/50

the bigger one is 1:25 (only if the model is smaller than the real thing, if the model is bigger, then the answer would be 1:50)
