I GIVE BRAINLIEST AND EXTRA POINTS

Round to nearest 10th find value of X

This doesn’t make sense to me it’s supposed to be lcm ( least common multiple )

Acollection of coins has value of 64 cents. there are two more nickels than dimes and three times as many pennies as dimes in this collection. how many of each kind of coin are in the collection?

Order the measurements from the least to the greatest. 2,720 ml , 24.91 l , 0.0268 kl
