how do you solve this problem? step by step
Sure! Here's a step-by-step solution:
1. Jannelle starts with 12.3 meters of fabric.
2. She uses 4.5 meters of fabric to make a dress.
3. To find the remaining fabric, subtract the amount used for the dress from the initial amount: 12.3 - 4.5 = 7.8 meters of fabric remaining.
4. Jannelle uses half of the remaining fabric to make a skirt. To find this, divide the remaining fabric by 2: 7.8 / 2 = 3.9 meters of fabric used to make the skirt.
So, Jannelle uses 3.9 meters of fabric to make the skirt.
