Answer:
A (Stone to Steel bridges)= 3:5
B (Steel to Stone bridges)= 5:3
C (Total bridges to steel bridges)= 8:5
Step-by-step explanation:
A: Stone to steel bridges is
12:20
You can simplify that by dividing by 4 on both numbers:
3:5
So the ratio of stone to steel bridges is 3:5
B: Steel to stone bridges is
20:12
You can simplify that by dividing by 4 on both numbers:
5:3
So the ratio of stone to steel bridges is 5:3
C: Total bridges to steel bridges is
What is the total number of bridges?
20+12=32
32:20
You can simplify that by dividing 4 on both numbers:
8:5
So the ratio of the total number of bridges to steel bridges is 8:5
Hope this helps!
