Question

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

Answer 1

Answer:

The difference is about $\frac{4}{25}$ of an ounce

Step-by-step explanation:

we know that

A small bat weighs about 2/5 of an ounce

A small hummingbird weighs about 14/25 of an ounce

step 1

Multiply 2/5 by 5/5

Remember that

5/5 is 1

so

$(\frac{2}{5})(\frac{5}{5})=\frac{10}{25}$

step 2

To find the difference in the weights of these animals, subtract the weight of the small bat from the weight of the small hummingbird

$(\frac{14}{25})-(\frac{10}{25})$

Remember that

When subtract fractions with the same denominators, subtract the top numbers and put the answer over the same denominator

so

$(\frac{14}{25})-(\frac{10}{25})=\frac{4}{25}$

therefore

The difference is about $\frac{4}{25}$ of an ounce
