6) The answer is (d).

We have,

0.00001131 =1.131×0.00001

= 1.131/100000

= 1.131×10^-5.

So, this is correct answer.

7) This question have two answers (b) and (c), both are correct.

(b) 480000-97000

= 4.8x100000-9.7x10000

=4.8x10^5-9.7x10^4

(c) 4.8x10^5-9.7x10^4

= 4.8x10^5-0.97x10^5

= (4.8-0.97) x10^5

=3.83x10^5

8)(a)

(4 x 10^3)(5x10^7).

= 4x5x10³x10^7

= 4x5x10^(3+7).

Can you please solve this problem?
shtirl [24]

Turn the fractions into decimals by dividing the top number by the bottom number, then multiply that by 100 to make it a percentage:


34/40 = 0.85 x 100 = 85%

20/25 = 0.80 x 100 = 80%

53/60 = 0.883 x 100 = 88.3%


The Last one is the highest percentage, so 53/60 is the best score.
