The easiest way is to make sure the fractions have the same denominators and are improper fractions. So another way to write it is : 4/15 + 5/15. Then you can add the numerators together making the numerator 9. The denominator will stay the same.
9/15
Since it is not simplified, divide both sides by three:
3/5
No, it's not a positive flow. If you're wasting more money than what you earn, you'll have a negative cash flow. It's false
8/10. If you simplify it, it will be 4/5
hope this helps.
Answer: No
Step-by-step explanation:
To find out if it is a right triangle then use the formula a^2 + b^2 = c^2 where a and b are the legs which are the two small sides and c is the hypotenuse the longest side. Input the values for a, b, and c and solve.
a = 12
b = 16
c= 25
12^2 + 16^2 = 25^2
144 + 256 = 625
400 = 625
This means that it is not a right angle because 400 does not equal to 625.
