Question

Esparanza rolls a number cube and gets a six 8 times. Based on this experiment, she predicts that if she rolls the cube 1,600 times, she would get a six 640 times. How many times did she roll the number cube in her experiment? Explain your reasoning

Answer 1

If you work out the fraction of 1600 that 640 you can apply this to the number of 6s, that she based this off of.
640÷1600=0.4
To calculate the number of times she rolled the dice you do 8÷0.4=20.
Therefore she rolled the cube 20 times to get 8 6s.
