Can u pls help me with this question

The correct answer is D, 6/8.

Step-by-step explanation:

For ratios or fractions an equivalent fraction has the same value but just more pieces. Think of it like a pizza. But to make sure they are equivalent you have to multiply or divide them by a fraction equal to 1. In other words the numerator and the denominator have to be the same number. So, when we multiply 3/4 by 2/2 you get 6/8 because 3 x 2 = 6 (numerators) and 4 x 2 = 8 (denominators).

If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe and please mark brainliest! :)

To find out how much hair Elise cut off, we must multiply the amount of hair Fabriola cut off by the fraction/decimal Elise cut off:

5.25*0.75
=3.9375

Elise cut 3.9375 inches off or 3.94 inches, if rounded to the nearest hundredth.

Hope this helps.
