Which pair of measurements is not equivalent? A) 6000 ml 6L

B) 4.5 450 ml

C) 9500 ml 9.5 l

D) 0.3 1 300 ml

4.5l and 450ml are the pair of measurements which is not equivalent

Solution:

Let us solve each pair of measurements to find which is not equivalent

first pair: 6000 ml and 6 L

To compare both quantities, they must be in same units. Let us convert them into same units

we know that 1 liter = 1000 milliliter

Hence 6 liter = 6000 milliliter

Hence both are equivalent. This pair is correct

Second pair: 9500 ml and 9.5L

Hence both are equivalent. This pair is correct

Third pair: 4.5L and 450 ml

Both are not equivalent

Fourth pair: 0.3 L and 300ml

Hence both are equivalent. This pair is correct

Thus 4.5l and 450ml are not equivalent.
