6,500 is 6.5 x 10 to the third power not 6.5X10 to the second

Answer:

6,500 = 6.5 × 10² is not written correctly.

Step-by-step explanation:

In the scientific notation we write a very large or very small number in easy notation of the product of a number between 0 to 9 and exponent of 10,

For this,

If we move decimal to the left side then the exponent of 10 is positive number of shifting,

While, if we move decimal to the right side then the exponent of 10 is negative number of shifting,

By the above explanation,

1207000=1.207\times 10^6

6500=6.5\times 10^3

901=9.01\times 10^2

402000=4.02\times 10^4

Beth=1782

Charlie=2970

Step-by-step explanation:

From the question we are told that

Ratio 6:9:15

Total amount to e shared N=£5940

Generally the Ratio can divide the Total amount mathematically as follows

Ratio

6:9:15/3=2:3:5

Sum of ratio

2+3+5=10

For Aaron

A=\frac{2}{10} *5940

A=1188

For Beth

B=\frac{3}{10} *5940

B=1782

For Charlie

C=\frac{2}{10} *5940

C=2970

Check answer

A+B+C=5940\\1188+1782+2970=5940
