10/8, since you need to multiply 5 by 2 since 4 was multiplied by 2.

The denominator is the number beneath the slash ( / ). So in 5/4 the denominator is 4. We have to convert this 4 into an 8.
So 4x2 = 8.
Since you multiplied the bottom part of the fraction (denominator) by 2, you have to also multiply the top part (numerator) by 2.
So 5x2 = 10. So the answer is 10/8.
Why is 10/8 a fraction equivalent to 5/4? Because you are multiplying 5/4 x 2/2 (and 2/2 = 1). So 10/8 and 5/4 are the same thing but with different denominators and numerators.
Hope it helps â

Well, you see that you need to multiply 4 by 2 in order to turn the 4 into an 8.
If you multiply the 4 by 2, you have to multiply the 5 by 2. (In order to keep the proper ratio, you need to always multiply the numerator and denominator by the same number)
So, the equation looks like:
(5/4)(2/2) = (10/8)
Remember, 2/2 = 1/1
So, basically you are multiplying 5/4 times 1!
Any number times 1 is the same number.
This is how you know the two numbers (5/4) and (10/8) Are the same value.
Therefore, 5/4 = 10/8.

take 5 times 2 because 8 is 2 times bigger than 4
