Answer: Lucy bought 1.5625 kilograms of potatoes.
Step-by-step explanation:
To find out how many kilograms of potatoes Lucy bought, we first need to determine the weight of the carrots and then subtract it from the total weight of the vegetables.
Given Total weight of vegetables = 2.5 kg
Now, we need to find the weight of the carrots.
We know that 3/8 of the vegetables are carrots.
Weight of carrots = (3/8) * 2.5 kg
To calculate this, we can multiply the fraction by 2.5:
Weight of carrots = (3/8) * 2.5 kg = (3 * 2.5) / 8 = 7.5 / 8 = 0.9375 kg
Now, we'll find the weight of the potatoes:
Weight of potatoes = Total weight of vegetables - Weight of carrots
Weight of potatoes = 2.5 kg - 0.9375 kg = 1.5625 kg
