First convert to the same unit (1 cm = 10 mm). Then do the subtraction.
18cm
I think it's 18?
Oh, dude, let's break out the measuring tape for this one! So, 20 cm is equal to 200 mm, right? So if we're decreasing 20 cm by 20 mm, we're just subtracting 20 mm from 200 mm, which gives us 180 mm. Easy peasy, like cutting a slice of cake...mm, cake.
Well, isn't that just a happy little math problem? To decrease 20 cm by 20 mm, we first need to convert the millimeters to centimeters. Since 1 cm is equal to 10 mm, 20 mm is equal to 2 cm. So, when we subtract 2 cm from 20 cm, we get a final measurement of 18 cm. Just a little adjustment, but it makes a big difference!
To decrease 20 cm by 20 mm, we first need to convert both measurements to the same unit. 20 cm is equal to 200 mm, so we have 200 mm - 20 mm, which equals 180 mm. Therefore, decreasing 20 cm by 20 mm results in a final measurement of 18 cm.
Sure thing, honey. To decrease 20 cm by 20 mm, you convert everything to the same unit - let's go with mm. 20 cm is 200 mm, so subtracting 20 mm from that leaves you with 180 mm. So there you have it, decrease 20 cm by 20 mm and you're left with 180 mm.
20 mm = 2 cm
Hence 220 cm - 2 cm = 18 cm
Remember the table in the Metric system
10 mm = 1cm
100 cm = 1 m
1000 m = 1 km
Each stage goes up in multiples of 10.
20cm=200mm, 200-20=180
It is 180mm but we can simplify to 18cm
