Here is Tylers strategy to find 15.28 – 8.73 . First, I add 0.27 to 8.73, then I add 6 more and 0.28 more. Explain why Tylers method works and use it to find the difference of 15.28 – 8.73

15.28 - 8.73 = 6.55

Step-by-step explanation:

Given - Here is Tylers strategy to find 15.28 – 8.73 . First, I add 0.27 to 8.73, then I add 6 more and 0.28 more.

To find - Explain why Tylers method works and use it to find the difference of 15.28 – 8.73

Proof -

If we add 0.27 to 8.73 , we get

8.73 + 0.27 = 9

Then add 6, we get

9 + 6 = 15

Then add 0.28 we get

15 + 0.28 = 15.28

As after adding 0.27 and 6 and 0.28 more to 8.73 gives the value 15.28.

So,

Tylers method works

Now,

By using Tylers method , we get

15.28 - 8.73 = 0.27 + 6 + 0.28

                    = 6.55

i.e. we get

15.28 - 8.73 = 6.55

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
