Answer 3

Calculating the Remaining Fabric

To calculate the percentage of fabric remaining after two successive cuts, we can use the following steps:

1. First, we calculate the fabric remaining after the first cut, which is 30% of the original fabric. 2. Then, we calculate the fabric remaining after the second cut, which is 45% of the fabric left after the first cut.

Let's proceed with the calculations.

Calculation

1. First Cut: - After the first cut, 30% of the fabric is left. - This means 70% of the fabric was cut off. - So, the fabric remaining after the first cut is 70% of the original fabric.

2. Second Cut: - After the second cut, 45% of the remaining fabric is left. - This means 55% of the fabric left after the first cut was cut off. - So, the fabric remaining after the second cut is 55% of the fabric left after the first cut.

Final Percentage of Fabric Remaining

To find out how much fabric is left after both cuts, we multiply the percentages:

70% (remaining after the first cut) * 45% (remaining after the second cut) = 31.5%

So, 31.5% of the original fabric is left after both cuts.
