30cm is 300mm
1 cm = 10 mmThen 30 mm is larger than 1 cm.
10 mm = 1 cm so 30 mm = 30/10 = 3 cm. Simple!
1 cm = 10 mm 2 cm = 20 mm . . . 9 cm = 90 mm 10 cm = 100 mm 20 cm = 200 mm 30 cm = 300 mm
I have a question and I don't know how to solve it!!!!
30mm converts to 3cm. Divide mm by 10 to get cm
Well, There are 10 mm in 1 cm, so 10 times 30 is 300 300 mm are in 30 cm
3.4 cm equals 34 mm which is greater than 30 mm
300 mm = 30 cm
1 cm = 10 mm ⇒ 3 cm = 3 x 10 mm = 30 mm
To compare the sizes of 3.4 cm and 30 mm, we need to convert them to the same unit. Since 1 cm is equal to 10 mm, 3.4 cm is equivalent to 34 mm. Therefore, 30 mm is smaller than 3.4 cm.
5 cm X 10 mm/cm = 50 mm 2 cm X 10 mm/cm = 20 mm 50 mm - 20 mm = 30 mm The answer is 30 mm.
10 mm = 1 cm 20 mm = 2 cm 30 mm = 3 cm . . 70 mm = 7 cm
