Answer:
5/6
Step-by-step explanation:
fractions! exciting :D
what you wanna do is get them to a common denominator, or bottom. In this case, the least common factor between 2 and 3 is six. To get that common denominator we should cross multiply-
That is, we'll take the denominator in 1/2, 2, and multiply it to both the numerator and denominator of our second fraction, making it 2/6. 2/6 is equal to 1/3 ! We can then do the same from 1/3 to 1/2, multiplying both 1 and 2 by three. That gives us 3/6 , which is equivalent to 1/2! I'mma include a visual below to make sure this makes sense because I may not be explaining it the best.
So, now we have 3/6 + 2/6 , and because we have common denominators we can just add across the top. That gives us 5/6 as the final answer.
Given
gas prices are now $3.75 and it up 10% from 6 months ago.
Find out how much were gas prices 6 months ago.
To proof
gas prices now = $3.75
let the gas price 6 month ago = x
gas price now is rise up 10% from 6 months ago
First write 10% in simpler form
= 0.1
Now the equation becomes
0.1x + x = 3.75
1.1x = 3.75
x = 3.41 (approx)
Thus gas prices 6 months ago be $ 3.41 (approx )
Hence proved
