The equivalent expression to 36 + 81 is 9(4 + 9).
It is in decimal form, can you give a little more feedback as to what you are applying?
I believe the question is saying - Confetti is dropped at x height and a person stands at y high, whats the difference between x and y. If the confetti falls at z speed, how long does the person have to wait until the confetti has fallen, to unsure he does not get hit.
Not entirly sure and can't work it out 100% as i would need all tables, charts and questions.
Since Chloe collected 4 times as much as her friend, who collected 1/6 a bag, you will have to multiply 4 by 1/6 to find how much Chloe collected.
To multiply fractions, you multiply the numerators and multiply the denominators. Then you put the product you got from multiplying the numerators over the product you got from multiplying the denominators. Remember that 4 is the same as 4/1. Simplify the product if needed.:
Chloe collected 2/3 of a bag.
