What is sum of 7 over 9 plus 1 over 6?

Answer 1

This can turn into a decimal problem or a fraction problem. Generally the terms in the problem mean:

Sum = Add

Over = Divide (or fraction)

So the equation ends up looking like this:

?=7/9+1/6

Fraction Answer:

to add them as fractions, you have to make the denominators equal. To do this, simply find the lowest common number they can both be divided into. For 9 and 6 this would be 18 (18/9=2, 18/6=3). Now, to change the denominators to 18, you have to change the numerators the same way, like this:

7*2=14 1*3=3

9*2=18 6*3=18

So the equation turns into:

?=14/18+3/18

To add fractions, simply add the numerators together:

14+3=17

So the answer is:

17/18

Decimal Answer:

Now, if you doing all of the processes, including the division (instead of just keeping them as fractions) you can do it 2 ways.

The first way is just do all the math:

?=7/9+1/6

Do the division first:

7/9=.778 1/6=.167

which turns it into:

?=.778+.167

.778+.167=.945

OR

The second way is to do the fraction method above and simply divide your answer:

17/18=.944

Answer 2

Mathematically: 7/9 + 1/6 = (14 + 3)/18 = 17/18 = 0.9444444
