So when you subtract by a negative number, it is the same thing as adding the two numbers.
First find a the LCD, or the least common denominator.
LCM(7,6) = 7•6 = 42
Then make the fractions have 42 as a denominator.
7 5/6 • 7/7 = 7 35/42
4 1/7 • 6/6 = 4 6/42
Finally, add the two mixed numbers
7 35/42
+4 6/42
11 41/42
So 11 41/42 is your answer
Answer:
If you need to find the hypotenuse, then square the two sides and add them together then square root that answer to get the hypotenuse. If you need to find a side then take the hypotenuse and other side and square them then subtract the side by the hypotenuse and then square root that answer.
Step-by-step explanation:
legs; a b hypotenuse c
a^2 + b^2 = c^2 then square root this answer
c^2 - b^2 = a^2 then square root this answer
c^2 - a^2 = b^2 then square root this answer
You have to add the whole numbers, which is 5 + 2 = 7. Then you add the fractions. In order to do that, you have to convert 4/9 to X/36 so 15/36 and 4/9 have the same denominator. In this case, 9 is a factor of 36, so you can multiply 4/9 by 4/4 (which is like multiplying by one). The result is 16/36. Now add the numerators 15 + 16 = 31. Denominator remains 36 because you do not change it when you add fractions.
The result therefore is 7 and 31/36.
4.4×.1=.44
4.4-.44=3.96
your answer is $3.96
