What is 2.5 x 12.34 give a good explanation

slega [8]

Answer:

30.85

Step-by-step explanation:

1. Put the 12.34 on top to make things simpler

then just multiply each number as if the decimals weren't there to begin with.

Your answer should look way too big, but when you finish multiplying count how many decimal places were in the two numbers, for this it would be 3 since there is a 5, 3, and 4 behind the decimal places.

You have to count 3 decimal places in your final answer to get the right solution! Any 0's trailing behind can be removed as well.

Hope this helps!!!

Dahasolnce [82]

Answer:

The total number of students in the gymnastics are <u>70</u>.

Step-by-step explanation:

Given:

Fifty-six students in a gymnastics club participated in the last fundraiser.

In the gymnastics club 80% of the students in the club participated in the fundraiser.

Now, to find the total number of students in the gymnastics.

Let the total number of students be $x.$

Number of students participated in the club = 56.

Percent of students participated in the club = 80%.

According to question:

$80\%\ of\ x=56$

$\frac{80}{100} \times x=56$

$0.8\times x=56$

<em>Dividing both sides by 0.8 we get:</em>

$x=70.$

Therefore, the total number of students in the gymnastics are 70.
