Answer :

To determine how many #5 notes are equivalent in value to four #200 notes, follow these steps:

1. First, understand the value of each note.
- A single #200 note has a value of 200 units.
- A single #5 note has a value of 5 units.

2. Calculate the total value of four #200 notes.
- If one #200 note is worth 200 units, then four #200 notes are worth:
[tex]\( 200 \times 4 = 800 \)[/tex] units.

3. Determine how many #5 notes are needed to make up 800 units.
- Each #5 note is worth 5 units.
- To find out how many #5 notes are in 800 units, divide 800 units by 5 units per note:
[tex]\( 800 \div 5 = 160 \)[/tex].

So, there are 160 #5 notes in the value of four #200 notes.

Thus, the number of #5 notes is 160, and the total value is 800 units.
