Step-by-step explanation:
2 ft / 1 second
and now
x/10 foot / 1/4 second
we need to multiply the original ratio by 1/4 to get the same denominator :
2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)
how many 10th foot are 1/2 ?
we need to bring 1/2 to the denominator of 10.
1/2 = x/10
10 = 2x
x = 5
so, 1/2 = 5/10
therefore, or answer is
5/10 foot / 1/4 second
