There are 10 centimetres in one decimetre. Therefore, 4.5 decimetres is equal to 4.5 x 10 = 45 centimetres.
There are 10 millilitres in one centilitre. Therefore, 45 centilitres is equal to 45 x 10 = 450 millilitres.
45 meter sq. (area = length * width)
There are 10 millimetres in one centimetre. Therefore, 45 millimetres is equal to 45 / 10 = 4.5 centimetres.
100 doesn't belong. All th others are equal.
23 = 68 - 45 = (4 x 17) - (5 x 11) + 10
45 x 45 = 2025
There are 10 grams in one decagram. Therefore, 4.5 grams is equal to 4.5/10 = 0.45 decagrams.
x would equal sqrt(45) which is ± 6.7082 (to 4 dp)
10% of 45 is 4.5 .1 x 45 When doing 10% of something, move the decimal to the left once.
= 100 cm ⇒ 45 m = 45 x 100 cm = 4500 cm
The question is meaningless. 10 m x 3 m x 6 m = 180 cubic metres. It cannot equal any number of square metres.
