Answer:

30/72 in simplest form is 5/12

Step-by-step explanation:

Find the prime factors of the numerator of given fraction 30/72.

Prime factors of 30 = 2 x 3 x 5

Do the same thing for the denominator

Prime factors of 72 = 2 x 2 x 2 x 3 x 3

Rewrite the fraction 30/72 in the form of prime factors

\frac{30}{72}= \frac{(2 x 3 x 5)}{(2 x 2 x 2 x 3 x 3)}

The x in the equation stands for multiply

Check and cancel the factors of 30 and 72 if any factors in the numerator and denominator can be canceled each other in the above fraction of prime factors

\frac{(2 x 3 x 5)}{(2 x 2 x 2 x 3 x 3)} \\\frac{( 5)}{( 2 x 2 x 3)}

Simplify and rewrite the fraction and you will get 5/12

Hope this helps

Richard and Teo have a combined age of 37. Richard is 4 years older than twice​ Teo's age. How old are Richard and​ Teo?
valkas [14]

Answer:

Teo is 11 years old and Richard is 26 years old.

Step-by-step explanation:

Let R be the age of Richard and T be the age of Teo.

<u><em>First set up the equations:</em></u>

The combined age of Teo and Richard is 37:

R+T=37

Richard is four years old than twice Teo's age:

R=2T+4

<u><em>Then, solve the equations:</em></u>

Substitute (2) to (1) and solve for T:

(2T+4)+T=37

3T=11

T=11

Solve for R using (2):

R=2(11)+4

R=22+4

R=26
