You could add together all the digits and then see if that is divisible by three. For example the number 345. 3 + 4 + 5 = 12. 12 is divisible by 3 therefore this number is too.

Hope This Helps You!
Good Luck Studying :)

If your number is quite large, like 3 digit or higher than that, then calculate the sum of their digits, if they will be divisible by 3, then the number is divisible, otherwise not.

For example. - "11055" 
Here, sum of digits = 1 + 1 + 0 + 5 + 5 = 12
As 12/3 = 4 (Divisible)

In short, This number would be divisible.

Hope this helps!

Use the spinner below to find the probability of getting the following number after 1 spin. P(multiple of 3) = (Round to 4 decim
Talja [164]

The value of the probability P(multiple of 3) is 0.3333

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

  • Total section = 12
  • Multiples of 3 = 4

The probability is then calculated as:

P(multiple of 3) = Multiples of 3/Total

This gives

P(multiple of 3) = 4/12

Evaluate

P(multiple of 3) = 0.3333

Hence, the value of the probability is 0.3333

A video sharing website starts with 20,000 members. Each year it loses 25% of the members, but adds 10,000 new members after the
MrMuchimi
20,000 x 25 = 500,000
500,000 divided by 100 = 5,000 members are lost.
Members left = 15,000
Members added = 10,000
Members every year  = Members left + Members added
                                   =          15,000 +  10,000
                                   =          25,000

nikitadnepr [17]

Good morning,

Answer:

<h2>5+(-4) > -4 + (-7)</h2>

Step-by-step explanation:

5+(-4) = 5 - 4 = 1

-4 + (-7) = -(4+7) = -11

since  1 > -11 then 5+(-4) > -4 + (-7)
