That's the same as 1.024 ÷ 10⁴

Each time we divide by 10 we move the decimal point one place to the left. If we have to we add zeros at the front.

1.024 ÷ 10⁴ = 0.1024 ÷ 10³ = 0.01024 ÷ 10² = 0.001024 ÷ 10 = 0.0001024

Answer: 0.0001024

The answer is 200-/2605

Please can someone help me answer these questions? Would be really grateful if it was done by the 12th of January. Thank you :) xo

Jon earned $38,000 last year. He paid $6,840 for entertainment. What percent of his earnings did Jon pay in entertainment expenses? Please tell how you got it.

Answers

If you would like to know what percent of earnings did Jon pay in entertainment expenses, you can calculate this using the following steps:

x% of $38000 is $6840
x% * 38000 = 6840
x/100 * 38000 = 6840
x * 380 = 6840 /380
x = 6840 / 380
x = 18%

The correct result would be 18%.

18% of his earnings went towards entertainment expenses. I used the "is over of equals percent over 100" formula. I then cross multiply then divide. My work is shown.
