7/9 as a decimal is 0.777.
7/9 is basically saying 7 divided by 9.
Since 9 doesn't at all go into 7, we have to make a decimal using long division.
So because a decimal isn't a whole number, we put 0.(blank) at the top in place of the regular number.
After, you just continue with the regular long division, but every time the divisor doesn't go into the number from the subtraction, you bring down a zero.
Sorry if this was kind of confusing!
Just watch a video on it if this didn't help.
Answer:
8 gallons
Step-by-step explanation:
#1: Set up a ratio from the recipe: gallons of punch to the number of people.
2 gallons 15 people
#2: Set up a ratio of gallons to the people coming to the party.
(Place the gallons on top) x gallons 60 people
#3: Set up a proportion 2 gallons x gallons
15 people = 60 people
* Like units should be across from each other
4) Solve using the "lonely mate" formula
2 gallons x gallons
15 people = 60 people
2 x 60 = 120
120/15 = 8
This means she should make 8 gallons.
Answer:
g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12? g (2) = x2 - 6x – 12?
