Answer:
The correct option is 1.
Step-by-step explanation:
The given expression is
To solve these type of expressions we have a rule that is known as BODMAS.
BODMAS = brackets of division, multiplication, addition, subtraction.
It defined the order of calculations. It means first we have solve the brackets, then division, then multiplication, after that addition and last subtraction.
So according to BODMAS, Claudio should simplify the bracket first.
The bracket of given expression is (7.1+0.5).
The simplification of given expression is shown below.
(Brakets)
(Multiplication)
(Addition)
Therefore he will solve (7.1+0.5) first. So, option 1 is correct.
Probability of choosing pink balloon is .
Step-by-step explanation:
Given,
Number of green balloons = 5
Number of yellow balloons = 3
Number of red balloons = 4
Number of pink balloons = 8
Total number of balloons = 5+3+4+8 = 20
To find the probability of pink balloon.
Formula
Probability of an even = number of outcomes ÷ total number of outcomes
So,
Probability of choosing pink balloon = =
Answer:
7
Step-by-step explanation:
English:
Which digit should go in the box to
make the next number divisible
between 2, 3 and 9? 8 ,? 48
Let x be the number, then the number will look like this:
8x48
This number is already divisible by 2, because it ends with an even number.
Now we need to check for divsibility by 3.
For this to be divisible by 3, the sum of the digit should be a multiple of 3.
We know if a number is divsible by 9, it is also divsible by 3.
So
The least positive solution is
Therefore 8748 is divsible by 2,3, and 9.
