Question

Sarah has built a scale model of a bridge. The bridge is 56ft across and 22ft wide. Sarah’s model is 8in across and 2.5 in. wide. Is Sarah’s model a trye model of the bridge? Explain

Answer 1

I'm guessing it's supposed to say "true" model not "trye" model?

in that case, you just need to see whether 56 feet by 22 feet is proportional to 8 inch by 2.5 inch

you can try dividing the longer dimension/smaller dimension for both cases and see if they're equal (basically, 56/22 vs. 8/2.5)
