4.5l and 450ml are the pair of measurements which is not equivalent
<u>Solution:</u>
Let us solve each pair of measurements to find which is not equivalent
<em><u>first pair: 6000 ml and 6 L</u></em>
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
<em><u>Second pair: 9500 ml and 9.5L</u></em>
Hence both are equivalent. This pair is correct
<em><u>Third pair: 4.5L and 450 ml</u></em>
Both are not equivalent
<em><u>Fourth pair: 0.3 L and 300ml</u></em>
Hence both are equivalent. This pair is correct
Thus 4.5l and 450ml are not equivalent
