Answer: 90%
Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.
So to write 9/10 as a percent, we need to find a fraction
equivalent to 9/10 that has a 100 in the denominator.
We can do this by setting up a proportion.
So we have 
.
Now, we can use cross-products to find the missing value.
So we have (9)(100) which is 900 <em>is equal</em> to (10)(n) or 10n.
So we have 900 = 10n.
Next, dividing both sides of the equation by 10, we have <em>90 = n</em>.
So, 9/10 is equal to 90/100 or 90%.
OK, so to simplify the left hand side, we need to multiply -12 and -5 to get our final exponent for j, therefore we get j^60 = j^t,so t=60 is your answer
It would be 24 total windows and 20 windows without leaks. You could possible write it as 24:20 or 24 to 20 or 24/20.
C - 30%.
We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error.
So it would be:
87.5/ 125 = 0.7
And 1-0.7 = 0.3
When we move the chemical place two places to the left to make it a percentage, it will become 30%.
Answer:
4
