6 divded by 2/3 = what

Answers

you keep the first number the way it is, and multiply by the reciprocal of the second number so:

6/1 * 3/2

6*3=18
1*2=2

So then you have 18/2 which is 9

Answer: 9

Explantion:

Divide: 6 : 2/

= 6/

· 3/

= 6 · 3/

1 · 2

= 18/

= 2 · 9/

2 · 1

= 9

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 2/

is 3/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 2 gives 9/

In words - six divided by two thirds = nine.

Admission to the museum is $12 for children and $15 for adults. On a certain day 2450 people go the the museum and $33,456 is collected How many adults and children went to museum

___children
___adults

Answers

c = children
a = adults

12c + 15a = 33456 (price)
c + a = 2450 (people)
c = 2450 - a (rewrite^)

12(2450 - a) + 15a = 33456 (substitute into the price equation)
29400 - 12a + 15a = 33456
3a = 4056
a = 1352

c = 2450 - (1352)
c = 1098

1098 children
1352 adults

A spinner has three equal sections of red, blue, and yellow. If the spinner is spun 250 times how many will the spinner land on a color that is not blue.

Answers

There are three equal sections on the spinner: one is red, one is blue, and one is yellow.

From this, we can figure out that the probability of the spinner landing on the blue section is 1/3. Thus, the probability of the spinner not landing on the blue section is 1 - 1/3 or 2/3.

Therefore, if the spinner is spun 250 times, and we are trying to figure out how many times it WON'T land on blue, then we multiple the probability of this happening (2/3) by the number of times that we spin the spinner (250).

2/3 * 250 = 166 2/3

If the spinner is spun 250 times, it will land on a color that is not blue 166 2/3 (approximately 167) times.

Answer:

167 if you round it up.

What’s the relationship between rational numbers and irrational

Answers

Answer:

Rational number can be represented as fraction which has prime numerator and denominator. Rational numbers are either limited or the pattern after some decimals repeats forever. For example

9/7=1.285714285714285714. As you see the pattern repeats limitless. Though Rational numbers can be limited Irrational numbers are always endless.

Often this values/constants are found in geometry like π=3.14, e=2.718, also √2 and so on. Themaindifferencebetweenrationalandirrationalnumbersisthatrationalnumberscanberepresentedbyfraction.

What number is fifteen sixty percent of

Answers

I'm pretty sure it is 25. A method you could use(calculator would be more quicker, but by hand works too) is dividing 15 by sixty percent. To do that, u find the decimal of sixty percent. You would move the decimal point of sixty(the original place of the decimal would be 60.0) two places to the left. Then 60% would become 0.60. But, you could simplify that to 0.6, then you do 15 divided 0.6. You would get 25. If you are doing it by hand, double check the answer by multiplying it with the decimal and you should get the original number(which is 15 in this case). I hope this helped :)
