Which brand is the cheapest? What is the cost of one napkin of this brand?

Which brand is the most expensive? What is the cost of one napkin of this brand?

Answers

Answer 1

Answer: The best way, in my opinion, to do this, is to find the unit rate of each napkin brand, or the cost per napkin. To do this, divide the money amount by the amount of napkin they give you.

/Brand W:2.87/500=.00574 \
\Brand X: 1.27/200=.00635   \ These are the
/Brand Y: .62/100 =.0062   / cost per napkin.
  \Brand Z: 1.37/250=.00548 /

Which one out of these 4 values is the lowest value? Obviously the two with the 6 in the thousandths place are more expensive than the ones with the 5s in the thousandths place, so that already eliminates Brand Z and Brand W.

What do we have left?

Brand X: 1.27/200=.00635
Brand Y: .62/100 =.0062
Cool. Which of these is a smaller number? Tip: If the first number besides 0 is the same, check the next one! You should get that Brand Y is the cheapest! :) Hoped this helped!

Answers

1) The best thing to do here is to divide the two weights of the buses and fin out what you need to multiply it by.
100/50= 2.
Therefore, you've got to multiply the amount of people by 2.
10*2= 20
Therefore, it takes 20 people to pull a 100 ton bus.

2) Here, you should work out what each one is worth. Half of 40 is 20.
one fourth of 20 is 5. Therefore, half of 40 is larger.

3) The best thing to do is to divide 32 by 8, and then multiply the number of degrees by this.
32/8=4
110*4= 440
Therefore, the ball rotates 440 degrees in 32 seconds.

4) the best thing to do is to find what one part is worth- and to do this, you have to add together the amount of roses and divide this by the total roses.
4+6= 10
50/10= 5
The roses are 6 parts yellow, therefore, 6*5= 30, there are 30 yellow roses.

Geoffrey and his babysitter spent 20 minutes preparing dinner, 2 hours and 30 minutes playing board games, and half an hour making dessert. How many minutes did they spend doing these activities?

200 minutes
20 + 60 + 60 + 30 + 30 = 200

This is very simple!!

Don't worry, no need to panic.
.
Just add the number of minutes up!!
.
Write the numbers that you can see are evident down.
.
20... 2 hours and 30 minutes... no more.
.
BUT WAIT!!
.
Half an hour looks suspicious.
.
Isn't that 30 minutes?
.
Add that to our list.
.
Now, we have to convert 2 hours to minutes.
.
Arggggh!!
.
Don't worry, there's 60 minutes in an hour, so 60 x 2 is 120 minutes!!
.
Add em' up!!
.
20 + 120 + 30 + 30 is...
.
200 minutes!!
.
Or, 3 hours and 20 minutes.

Hope I helped!!
