Alright so all we are doing is adding 7/10 and 1/2
But sometimes that can be difficult because they don’t have the same denominator
In that case, we want to give them the same denominator (bottom number if the fraction)
So we do this by multiply 1/2 by 5/5 which will get you 5/10
We now have 5/10 and 7/10 which both have the same denominator (10)
So add them together and you will get 12/10
Now that’s more than 1 gallon so let’s figure out how much more
So 12/10 -10/10 (full gallon) = 2/10
So she used 1 2/10 gallons
If you want it in decimal form then it’s 1.2 (divide 2 by 10)
Hope that helped!
I did know of the understanding of math high school?
I believe it is 0 but I’m not exactly sure
Answer:
8.4cm
Step-by-step explanation:
first you have to square both sides
8²+4²= Hypotenuse (the diagonal)
you'll get
56 + 16
next you add it, and it'll equal 72
lastly you'll find the square root of that number
which is going to give you 8.4
