Answers

Answer:

It is 150 percent

Step-by-step explanation:

You can find this value by dividing the numerator by the denominator, summing this value to the integer part and multiplying the result by 100%, so:

1 1/2 in percent = (1 + 1/2) × 100% =

(1 + 0.5) × 100% = 1.5 × 100% = 150%

Hope this helps! Sorry if I'm wrong.

Answer:

150%

Step-by-step explanation:

112=1+12

i know that

is the same as

1÷2

Therefore:

112=1+(1÷2)

Then using

Long Division for 1 divided by 2

we have

=1+0.5=1.5

Converting our number to a percentage:

1.5×100

=150%

Suppose that you are in charge of selling hamburgers for your school fundraiser. You are selling hamburgers in your local community.
Which tray/plate should you use for the hamburgers?
How many hamburgers should you sell?
How many buns and meat patties should you buy to sell?
A styrofoam plate comes in packages of 14.
A sheet iron tray comes in packages of 12.
Buns are sold in packages of 12.
Meat patties are sold in packages of 18.
The school is counting on you to sell between 10-80 hamburgers.
You don't want any leftovers of anything.

I don't understand this question, can someone lend a hand?

Answers

Answer:

(I have first answered the 2nd question first to find out how many Iron trays I actually need)

A2-(This is kinda tricky)

If you want to make a hamburger you would want to have 2 buns and 1 patty.

So our equation will be-

x/18=2

(Also I am buying 18 patties)

(And the 2 is twice the patties I have)

x=18x2

x=36

And now to figure out how many packages (each of 12) I need to have to make Hamburgers without having any leftovers

So,

36/12

Therefore I would need 3 packages of Buns

A1-The number of Sheet Iron needed,

=> Number of Sheet Iron Tray=Number of Patties Bought

= 12x=36

= x=36/12

= x=3

Therefore you would need 3 packages of Iron trays

This question actually has different answers to it this is just an example of one of its answers.

If two possitive fractions are less than 1, why is their product less than 1

Answers

Answer:

The product of two positive fractions is also less than one because you are multiplying a number that is already less than 1. When you multiply 1/2 by 1/2 you do not get the 100% of the whole because you are only getting 50% of the 50% of the whole, which in turn is equivalent to 25% of the whole.

A music store buys a trumpet for $80. They want to make a 35% profit. What is the new price of the trumpet?

Answers

Answer: $108

Step-by-step explanation:

80 x .35 = 28

80+28= 108

35% just simply mean 35% more than the original price
So to solve this you to multiply the original cost($80) to 0.35
80(0.35)=$28
28 dollars is what they want to make in addition to the 80 they spent so
80+28=108
So the new price of the trumpet is $108 with profit
