To find an equivalent fraction, we need to divide both the numerator and denominator by the same value. In this case, the value is 0.01, which is the same as dividing by 0.01.

0.76 miles / 0.01 = 76 miles / 1

So the fraction equivalent to the distance left in her race is 76/1.

None of the given fractions, A, B, C, or D, are equivalent to 76/1.
A library loans out 3 books every day for a week and no books are returned. The following equation is written to represent the situation:
(−3)⋅7=−21
Which of the following best explains the meaning of
−21
in the equation?

A Books were loaned out for
−21
days.

B The library now has
−21
books.

C The change in the number of books at the library over the course of the week was
−21
.

D The number of books loaned per day was
−21
.
The correct answer is C.

In the equation, (-3) * 7 = -21, the -21 represents the change in the number of books at the library over the course of the week. Since 3 books are loaned out every day for a week, the total change in the number of books is -21. The negative sign represents a decrease in the number of books.
