Answer:
option D; 20/3 OR 6 2/3
Step-by-step explanation:
CONVERT THE HOURS INTO MINUTES;
3/4 × 60 = 45 mins
1hour = 60 mins
45 mins = 5 miles
60 mins = ??
cross multiply;
60 by 5 ÷ 45 to get 20/3.
Hey there!
Let's first evaluate this problem, and the keyword we need to use. The problem says that out of the total number of bracelets Brianna has, x, 1/3 of them are pink. The reason the word of is so important throughout math is that it signifies multiplication. For example, 1/2 of 10 is 5 because 1/2 times 10 is 5.
Now, to apply that to this situation, we need to create an equation, a mathematical statement that indicated the equilibrium or equality of two values. Since we have 1/3 of all her bracelets, x is four, we can set up our equation. Here's another good keyword- is. Is signifies an equation, because it means "equal to" mathematically. For example, 5 is equal to 20/4.
We have:
1/3(x) = 4
(One-third of x, the total amount of bracelets, is four.)
We don't want that fraction there. In order to get rid of it and keep the expression equal, we multiply both sides by 3. We have,
x = 12
Hope this helps!
