Solve 3/4+(1/3 : 1/6)-(-1/2)

i am not saying this is right but

Step-by-step explanation:

13

4

OR  

3

1

4

Step-by-step explanation:

first you work out what is in the brackets

that is  

1

3

÷

1

6

to give you 2 as you answer

second step rewrite the whole question replacing two in the place of  

1

3

÷

1

6

so you will have  

3

4

+

2

−

(

−

1

2

)

thirdly open the brackets with the negative sign outside the bracket that is:  

−

(

−

1

2

)

so that you get  

+

1

2

(or  

1

2

, basically)

lastly rewrite the whole question

so you will have  

3

4

+

2

+

1

2

, you add all of them ...  

3

4

+

8

4

+

2

4

=

13

4

EXTRA

you can keep that solution, or you can change it from improper fraction to a mixed number

if you use long division,  

13

÷

4

=

3

with a remainder of  

1

over  

4

.

doing this by calculator you get 3.25, which is basically  

3

25

100

=

3

1

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
