Final answer:
There are 2 road signs along the highway.
Step-by-step explanation:
To find the number of road signs along the highway, we need to divide the length of the highway by the distance between each road sign.
The length of the highway is given as 7/10 mile.
The distance between each road sign is given as 1/3 mile.
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
So, we will multiply 7/10 by 3/1.
When we multiply, we get (7/10) * (3/1)
= (21/10)
= 2.1.
Therefore, there are 2.1 road signs along the highway. Since we can't have a fraction of a road sign, we round down to the nearest whole number.
So, there are 2 road signs along the highway.
