How could you explain that 21/30 is greater than 2/3?

To begin with, 2/3 can also be written as 20/30
Now we see that 21 is greater than 20.
So, in this one way we can say that 21/30 is slightly greater than 2/3.
Still didnt understand?
Lets go deep down, Maybe converting the fraction to a decimal will be good.
So when we convert the fraction 21/30, it gives us the decimal value:0.7
The same thing with 2/3, it gives us a non-ending decimal value:0.6667
However, dont get confused by the fact that 0.66667 is so close to 0.7
Although it is close enough, 0.7 is still higher.
In closure, 21/30 is greater than 2/3

Well its greater than 2/3, because 2/3= 20/30, so 21/30 is greater.

You would set up a proportion 6/4 = 30/x you then can do what i call the fish and multiply 30 by 4 and the divide by 6 which will give you x which your answer is 20

You earn 60 dollars for mowing 5 lawns how much do you earn for mowing 15 lawns

Nookie1986 [14]

well 60/5=12

so you get $12 per yard

12*15=180

or you could notice that 5 goes into 15 3 times and then multiply 60*3 any way the answer is 180

In 2010, a city's population was 1,405,233 and it was decreasing at a rate of 1.1%. At this rate when will the city's population

frez [133]

The equation
                                            P(t) = 1405233 * (1 - 0.011)^(t)
models the population at t years after 2010. Then, when P(t) = 1,200,000, we have
                                 1200000 = 1405233 * (0.989)^t
                                  (0.989)^t = 1200000/1405233
                                                t = log(1200000/1405233)/log(0.989)
                                                t = 14.27 years
This means 14.27 years after 2010. Therefore, the answer to this question is 2024.

Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 ." What is Sara's number?

KiRa [710]

Statement given :

→Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 .

To find :

Sara's number

SOLUTION :

Let us take Sara's Number be “x”.

★According to Question,

→ x - 11×(-3)= -54

→ x + 33 = -54

→ x = -54-33

→ x = (-87)

let's verify our number,and check whether it's correct or not !

x - 11×(-3)= -54

Putting the value of x

(-87) - 11 × (-3)= -54

(-87) + 33 = -54

(-54) = -54

Hence, The L.H.S. = R.H.S.

Thus,our number is Verified.
