Add. 5/6 + 2 3/4 in simplest form.
Deffense [45]

okay so you would first turn everything into fractions 2 3/4= 11/4 + 5/6

next you would change the denominators so they match 11/4 x 6 = 66/24

5/6 x 4 = 20/24

so then you would add 66/24 + 20/24 = 88/24 = 11/3

11/3 is your answer



hope this helps!

Escribe un número de tres cifras digamos a1b1c1, en el cual a1 sea distinto de c1; ahora invierte los dígitos a1 y c1, (obtendrá
Delicious77 [7]

Answer:

El número obtenido es:

  • <u>1089</u>.

Step-by-step explanation:

Vamos a escoger tres números sencillos para cada variable como:

  • a1 = 1
  • b1 = 2
  • c1 = 3

Por lo tanto, nuestro número de tres cifras es:

  • 123 (la única pauta es que a1 sea diferente a c1 y con este número la cumplimos)

Ahora, nos dice que invirtamos los números a1 y c1, por lo tanto, nuestro nuevo número de tres cifras sería:

  • 321

A continuación, nos menciona que restemos el menor del mayor, en este caso, nuestro número menor es 123 y el mayor es 321, por lo tanto:

  • 321 - 123 = <u>198</u> (Este resultado será el mismo sin importar cuáles números elijas para el ejercicio)

Como obtuvimos el número 198, se podría decir que:

  • a2 = 1
  • b2 = 9
  • c2 = 8

Ahora nos piden que invirtamos a2 y c2, por lo tanto nuestro nuevo número sería:

  • <u>891</u>

Y por último, nos solicita que sumemos los dos últimos números obtenidos, entonces tenemos:

  • 891 + 198 = <u>1089</u>

Por lo tanto, <u>el número obtenido al final es 1089</u>, el cual obtendrás sin importar qué número de tres cifras elijas al inicio, siempre y cuando no se repitan el primero y el tercer dígito.
