First you have to convert the denominators to the Lowest Common Multiple (unless the denominators are equal, of course).
Example 1/4 + 1/2
The LCM of 2 and 4 = 4 so we can write 1/2 as 1*2/2*2 = 2/4.
Now we can add:-
1/4 + 2/4 = 3/4.
Same thing goes for subtraction.
Example 2:-
5/6 - 1/7 :-
LCM of 6 and 7 = 6*7 = 42 so we have:-
5*7 / 6*7 - 1*6 / 7*6
= 35/42 - 6/42 = 29/42
Your answer is 18 y=29/5x=18
Answer:
418.4
Step-by-step explanation:
The answer to this question is 36. The formula to find area of a square is a squared. By equating that formula to 83 and taking the square root of both sides, we get the value of one side which is 9.1. Then we multiply that value by 4 because all sides of a square have equal values. This our answer becomes 36.4 which is rounded to 36.
