The LCM of two numbers is 48. The number one in the ratio 2:3. Then Sum of the numbers is:
Oksi-84 [34.3K]

Answer:

40

Step-by-step explanation:

Let the numbers be 2x and 3x

Then their L.C.M. = 6x

BUT also their LCM=48

6x=48

x=48/6

x=8

So,

First number=2x=2x8=16

Second number=3x=3x8=24

The numbers are 16 and 24.

Hence required sum =(16+24)=40

So none of the options are correct

Una estrategia de cálculo mental con
Softa [21]

Esta estrategia se puede aplicar sumando  15,75 + 0,25, –1,8 + –0,20, 3,5 + 12,5 y 2,62 + 7,38 antes de sumar el tercer número dado en cada caso.

<h3>¿En qué consiste está estrategia?</h3>

La estrategia propuesta consiste en sumar dos números decimales que den como resultado un número entero antes de sumar el tercer número decima. Por ejemplo si teneos  1,4 + 0,6  + 1,2, se debe sumar primero 1,4 + 0,6 lo que es igual a 2 antes de sumar el 1,2.

<h3>¿Por qué utilizar esta estrategia?</h3>

Este estrategia es beneficiosa porque facilita sumar números decimales.

<h3>¿Cómo aplicar está estrategia?</h3>
  • 15,75 + 1,2 + 0,25 = 16 (0,25+15,75) + 1,2 = 17,2
  • (–1,8) + 2,45 + (–0,20) = -2 (-1,8-0,20) + 2,45 = 0,45
  • 3,5 + 11,8 + 12,5 = 16 (12,5+3,5) +11,8 = 27.8
  • 7,38 – 1,5 + 2,62 = 10 (7,38+2,62) + 2,62 = 12,62

Remmi wrote the equation of the line y=1/3(x+2) He solved for x and got x=3y-2 Which of the following is an equivalent equation
gregori [183]
<span>the equation of the line y = 1/3 (x+2)
to solve for x , multiply the whole eqaution by 3, which results to:
</span>[y = 1/3 (x + 2)] 3
3y = x + 2
then transpose the 2 to the other side of the equation
3y - 2 = x
x = 3y - 2
so the answer of remmi is correct. i hope this can help you, feel free to ask for clarifications
