3 1/2 + 4 5/6
Multiply 3 1/2 by 3/3 so that both fractions have "6" as their bottom number (denominator).
3 1/2 × 3/3 = 3 3/6
So, our new question is this : 3 3/6 + 4 5/6
Basically, when both fractions have the same bottom number (denominator), all you have to do is add the top numbers (numerators) as well as adding the whole numbers. Remember, you always keep the bottom number (denominator) the same when you are adding or subtracting.
Whole number : 3 + 4 = 7
Numerator : 3 + 5 = 8
Denominator : 6
So, our answer is 7 8/6
However, because the top number (numerator) is greater than the bottom number (denominator), you have to make the whole number larger.
So, our answer is 8 2/6
Simplify.
8 1/3

1/1x6/7 =6/7yd is the answer
Answer:
Step-by-step explanation:
Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:
Simplify: 
Divide both sides of the equation by 7 to get: 
<u>Answer:</u>
96
<u>Step-by-step explanation:</u>
Let's assume that the marks needed in the next exam is 
. Then if the average becomes 90,
Now we can simply solve for :
⇒ 
⇒ 
[Multiplying both sides by 4]
⇒ 
[Subtracting 264 from both sides]
⇒ 
Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.
