Question

monarch butterflies migrate when they sense daylight hours are shorter, temperatures get colder, and plant life gets weaker. write 2 equivalent fractions for the part of the migration a monarch butterfly can complete in 4 weeks. travel 4/5 of the total migration in 4 weeks choose the correct answer below. a. 8/10, 80/100 b. 8/10, 80/395 c. 8/15, 80/100 d. 8/15, 80/395

Explanation:

Step1: Recall Equivalent Fractions

To find equivalent fractions, we multiply or divide the numerator and denominator by the same non - zero number. The given fraction is $\frac{4}{5}$.

Step2: Find First Equivalent Fraction

Multiply the numerator and denominator of $\frac{4}{5}$ by 2.
For the numerator: $4\times2 = 8$
For the denominator: $5\times2=10$
So, $\frac{4\times2}{5\times2}=\frac{8}{10}$

Step3: Find Second Equivalent Fraction

Multiply the numerator and denominator of $\frac{4}{5}$ by 20.
For the numerator: $4\times20 = 80$
For the denominator: $5\times20 = 100$
So, $\frac{4\times20}{5\times20}=\frac{80}{100}$

Now we check the options. Option A has $\frac{8}{10}$ and $\frac{80}{100}$, which are equivalent to $\frac{4}{5}$.

Answer:

A. $\frac{8}{10},\frac{80}{100}$
