Simplyfiy 4 over 7 divided by 3 over negative 8

Answers

Answer 1
Answer:

(4)/(7)/(-3)/(8)

With division when using fraction the first fraction stays the same, but you will switch the division sign to multiplication and you will take the reciprocale (flip the numerator and denominator) of the second fraction like so...

(4)/(7)*(-8)/(3)

Now you can multiply normally:

(4*(-8))/(7*3)

(-32)/(21) <<<This is your answer

Hope this helped!

mrs Singh bought 9 folders 9 notebooks. The cost of each folder is $2.50 and the cost of each notebook is $4 write two equivalent expressions then find the answer

Answers

He bought 3 folders and 2 notebooks

  • Let the cost of folder books be x
  • Let the cost of notebooks be y

We are told that mrs Singh bought 9 folders and 9 notebooks,

If the cost of each folder is $2.50 and the cost of each notebook is $4, then;

2.5x = 9 and 4y = 9

Get the value of x:

2.5x = 9

x = 9/2.5

x = 3.6

Get the value of y;

4y = 9

y = 9/4

y = 2.25

Hence he bought 3 folders and 2 notebooks

What is 1/10 of 90000

Answers

The  $\n((1)/(10)) ^(th) of 90000 is 9000.

We have a number - 90000

We have to determine  $\n((1)/(10)) ^(th)part of this number.

Evaluate 1/5 of 100.

The $\n((1)/(5)) ^(th) part of 100 will be -

(1)/(5) * 100 = 20

According to the question, we have -

Number -   90000

Therefore, 1/10 of 90000 will be -

(1)/(10) * 90000 = 9000

Hence, $\n((1)/(10)) ^(th) of 90000 is 9000.

Mixed numbers between 5 and 7, with an interval of 1 / 3 between each pair of mixed numbers

Answers

Answer:

5,5(1)/(3),5(2)/(3),....6(1)/(3),6(2)/(3),....7

Step-by-step explanation:

To find : Mixed numbers between 5 and 7, with an interval of (1)/(3) between each pair of mixed numbers ?

Solution :

Mixed numbers between 5 and 7.

The interval is (1)/(3) between each pair of mixed numbers.

So, The number form as

5,5+(1)/(3),5+(2)/(3),....6+(1)/(3),6+(2)/(3),....7

In mixed fraction,

5,5(1)/(3),5(2)/(3),....6(1)/(3),6(2)/(3),....7

Therefore, The mixed numbers between 5 and 7, with an interval of (1)/(3) between each pair of mixed numbers are

5,5(1)/(3),5(2)/(3),....6(1)/(3),6(2)/(3),....7

5 1/3, 5 2/3, 6 1/3, 6 2/3....mixed numbers between 5 and 7.....intervals of 1/3

Sam paid $8.28 for 18 stamps.at this rate,how much will he pay to buy 12 stamps

Answers

HE WOULD PAY $5.52 FOR 12 STAMPS BECAUSE 8.28/18=0.46 THE YOU USE 0.46 X 12 = AND GET $5.52
lets find the cost per stamp by dividing the cost by # of stamps
$8.28/18 
=$0.46
so if that is the cost per stamp, multiply that by 12 to find the new total cost 
0.46x12
=5.52
