Question

Kate is a veterinarian.she has 9 liter bottles of a common liquid medicine for cats.she carefully measures 90 milliliters of the medicine into a smaller bottle and labels the bottle with each cats name.How many smaller bottles of 90 ml each she make from the 9 l bottles.

Answer 1

first, we convert 9 Liters to milliliter,, recall that
1 L = 1000 mL, thus
9 L = 9000 mL
now we divide 9000 by 90 to determine how many 90 mL-bottle she needs:
9000 / 90 = 100 bottles

hope this helps~ :)
