Answer:
Step-by-step explanation:
We can analyze the question as follows in order to get the correct interpretation.
1p coins = 3/8 of 640
= 3/8 × 640 = 240
5p coins = as many than 1p coins
This implies that 1p coins = 5p coins
hence = 240
The remainder is :
= 640 - (240 + 240) = 640 - 480 = 160
The remaining coins are 2p coins .
Our answer is therefore given by :
= 160 2p coins
