Elda has a rectangular piece of paper with an area of 0.12 m. she cuts this piece of paper into small rectangles each with an area of 200 cm.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

2+2=4

4-5=-1

is that your

10 x 12 = 120 the tens to conte like 10,20,30,40 so i did that 12 times
