2.4 x 24.12 I need someone to do it with me step by step

I made a PDF. Last time I tried doing this, the PDF did not work. Please tell me if the PDF is not working for you. My handwriting is also horrible XD. And sorry for my way of explaining, this is just how I was thought it, so it probably won't make sense.

So basically I'll try walking through what is going on in the picture.

So basically I just multiplied 2,412 by 24. I will incorporate the decimals later.

After multiplying, I got 57,888.

Now I will include the decimals.

You can see on the right side of the picture I counted how many decimal places 24.12 has. It has 2 decimal places.

Then I counted how many decimal places 2.4 has. It has 1 decimal place.

So I have to totally add the decimal places now.

2 decimal places plus 1 decimal place is 3 decimal places.

Three decimal places into 57,888 is 57.888.

2.4 × 24.12 is 57.888.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
