A simple way you could solve this is by drawing a tape graph.
Draw a long rectangular box.
Cut the box into 8 pieces, seeing as how 5/8 of the coins are dimes.
We have to take 48 and divide it by 8, we get 6, so now we know how many dimes are evenly split into each piece.
Now color in 5 pieces of the tape.
This represents the 5 in 5/8.
Now to find the number of coins, simply multiply 5 by 6, you get the answer of 30.
I hope this helps, if you are confused with any part of my explanation, ask and I will clarify.

Hey there, and good morning to you! :D
Vertical Angles are angles that are congruent and have the same measure, and they usually form a straight line through the vertex. (if you were to draw through them) They actually share the same vertex.
So if angle 1 and angle 5 are vertical angles, and angle 1 equals 55 degrees,
then angle 5 will equal 55 degrees.
I hope this helps!
