What’s does 3/5 + 1/3 equal

Step-by-step explanation:

3/5 + 1/3

taking lcm we get 15

= 3 * 3 + 1 * 5

          15

= 9 + 5

     15

=14/ 15

14/15

Step-by-step explanation:

To add fractions, we need to find a common denominator.

The common denominator is 15. An easy way to find a common denominator is to multiply the denominators. 3*5=15

Now, we need to make both fractions have the common denominator.

3/5

Multiply 3/5 by 3/3

3/5*3/3

Multiply across the numerator and denominator

9/15

1/3

Multiply 1/3 by 5/5

1/3*5/5

Multiply across the numerator and denominator

5/15

Now, we have common denominators and can add

9/15+5/15

Add only the numerator and leave the denominator as is

14/15

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
