Question

Spice Parisienne is two-fifths ounce ground clovesone and one-fifth ounces ground nutmeg and one and one-fifth ounces ground gingerone and one-tenth ounces cinnamon. Latisha buys spices to make one batch of Spice Parisienne. Use estimation to decide whether she buys more or less than 4 ounces of spices. Explain your reasoning.

Answer 1

To estimate whether Latisha buys more or less than 4 ounces of spices, we can round the given amounts to the nearest whole number.

Two-fifths ounce is about 0.4 ounce.

One and one-fifth ounces is about 1.2 ounces.

One and one-tenth ounces is about 1.1 ounces.

Adding these rounded amounts gives:

0.4 + 1.2 + 1.1 = 2.7 ounces

Since 2.7 ounces is less than 4 ounces, we can conclude that Latisha buys less than 4 ounces of spices to make one batch of Spice Parisienne.
