Q:

A small bat weighs about 2/5 of an ounce. A small hummingbird weighs about 14/25 of an ounce. Explain how to find the difference in the weights of these animals

Accepted Solution

A:
Answer:The difference is about [tex]\frac{4}{25}[/tex] of an ounceStep-by-step explanation:we know thatA small bat weighs about 2/5 of an ounceA small hummingbird weighs about 14/25 of an ouncestep 1Multiply 2/5 by 5/5Remember that5/5 is 1so[tex](\frac{2}{5})(\frac{5}{5})=\frac{10}{25}[/tex]step 2To find the difference in the weights of these animals, subtract the weight of the small bat from the weight of the small hummingbird[tex](\frac{14}{25})-(\frac{10}{25})[/tex]Remember thatWhen subtract fractions with the same denominators, subtract the top numbers and put the answer over the same denominatorso[tex](\frac{14}{25})-(\frac{10}{25})=\frac{4}{25}[/tex]thereforeThe difference is about [tex]\frac{4}{25}[/tex] of an ounce
