Answer 2

Calculation of Stitches per Minute

To find out how many stitches 18 sewing machines will make in 1 minute, we can start by calculating the number of stitches made by one sewing machine in 5 minutes.

Given: - 7 sewing machines made 52,500 stitches in 5 minutes

First, let's find out how many stitches one sewing machine makes in 5 minutes: 52,500 stitches / 7 machines = 7,500 stitches per machine in 5 minutes.

Now, to find out how many stitches one sewing machine makes in 1 minute: 7,500 stitches / 5 minutes = 1,500 stitches per machine in 1 minute.

Stitches Made by 18 Sewing Machines in 1 Minute

Now that we know one sewing machine makes 1,500 stitches in 1 minute, we can calculate the total stitches made by 18 sewing machines in 1 minute: 1,500 stitches/machine * 18 machines = 27,000 stitches in 1 minute.

Therefore, 18 such sewing machines will make 27,000 stitches in 1 minute.
