A group of biologists found a total of 15 loggerhead turtle nests along a beach during a certain season. This was 20% of the tot

Andre45 [30]

20% also equals 1/5, right?

So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.

15 x 5 = 75

There were 75 total nests

Write your numbet ad a mixed numbet in simplest form

Alex_Xolod [135]

Answer:

the answer is $2\frac{5}{12}$ hours

Step-by-step explanation:

so first we have to turn the fractions into mixed fractions, in order to do that we multiply the whole number by the denominator and add the numerator, our answer becomes the new numerator over the same denominator.

$3\frac{3}{4}$

3 x 4 + 3

12 + 3

$\frac{15}{4}$

we do the same thing again.

$1\frac{1}{3}$

1 x 3 + 1

3 + 1

$\frac{4}{3}$

then after we get our mixed fractions we subtract them from each other. Since the denominators are not the same we multiply to get the same denominators.

$\frac{15}{4}-\frac{4}{3}$

$\frac{15*3}{4*3}-\frac{4*4}{3*4}$

$\frac{45}{12}-\frac{16}{12}$

we subtract the numerators and keep the denominators.

$\frac{29}{12}$

then we simplify.

$2\frac{5}{12}$
