Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.

Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500

6% of what number is 270? 4,500 450 45 4.5

Gnoma [55]

So to solve this problem, we can either do guess and check, or solve an equation.

Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.

So, to begin, let's define our unknown.

We can represent the number as "n"

So, 6 percent of "n" is equal to 270

To find a "percent" of a number, you need to multiply the number by the percentage.

So, 6 percent as a decimal is .06

This is because a percent is a fraction divided by 100 (6/100)

$.6\times n=270\\\n=270\div.6\\n= 4500$

The number is 4,500

Can I get help on each one and not just answers please

1. To get the decimal, you divide 8 by 7 and add that to the back of ten. One eighth is .125. .125*7= 0.875, so your answer is 10.875.

2. A fifth is .2, so your answer is 9.8.

3. One ninth is .11..., which that repeating forever, so 8/9 is .89. You round the last eighth up.

4. 11 goes into 24 twice. Subtract 22 to get 2. Add a decimal and a zero. 11 goes into 20 once. Subtract 11 to get 9. Add another zero. 11 goes into 90 8 times. Subtract 88 to get 2. So your answer is 9.2. Sorry, it's hard to do long division on Brainly haha.

5. 6/27 is equal to 3*2/3*9, which is equal to 2/9. 2/9s is .22...

6. I can't see this one.

7. 8.7/1.4 is basically your problem. Move over the decimals in both of them so that you have 87/14 so that you can actually divide. So put them in long division format, and add a zero so you have 140. 87 goes in once, and you subtract 87 from 140 to get 53. Add another zero. 87 goes into 530 six times. Subtract 522 to get 8. Round .16 to .2 Your answer is .2

8. I'll teach you a fun property. Dividing is the same as multiplying by the reciprocal of something - or the upsidedown version. So if you have .1/1, then you multiply .365 by 1/.1. When you divide by .1, you get 3.65.

9. Do the same thing here. .01/1 flipped is 1/.01. You get 4270.9.

10. Move the decimal over the left three times: .00247

11. Move the decimal over to the left three times: .00039

12. Can't read all of this one.

Hope I helped!
