The Chinese text The Nine Chapters on the Mathematical Art (Jiu Zhang Suan Shu), from between 300 BC and AD 200, is the first example of the use of matrix methods to solve simultaneous equations. (Wikipedia)
To find 31 percent of 200 you will solve it like this: 31% of 200 is: 0.31* 200= 62. Using a calculator will also help.
Simply divide by 10. 20 hundreds equal 20 x 100, or 2,000. Divide 10 into 2000 and you get 200. 200 tens equal 20 hundreds. To check your work ask yourself, does 200 x 10 = 20 x 100? 200 x 10 = 2,000 and 20 x 100 = 2,000. The answer is correct.
To solve, think of it as something (b) over 5 is -40, which means that something divided by 5 is -40, so that something must be 5 times -40 or -200.
20 percent of 1000 = 200 20% of 1000 = 20% * 1000 = 20%/100% * 1000 = 200
make it into a proportion ..... 30/100= x/200 so.... 200 multiplied by 30 = 6000 then divide 6000 by 100 ......6000/100 =60 60 =x 60 is 30% of 200
Number*percent in a decimal 200 * .42 = 84

Okay, I'm assuming that you mean 5.25% copper by weight, otherwise there isn't enough information here to solve the problem. 5.25% of 200 lbs = 10.5 lbs
Solve it yourself
At most 200*400, 60*400, 4*400 and 264*10.If his arithmetic is any good, he could combine the first two into 260*400.
When you have problem shifting gears, you transmission has a problem.

The GCF of 200 and 5600 is 200. Since 200 is a factor of 5600, it is automatically the GCF of this problem.
200
First, change the percent to a decimal which is done by dividing by 100. Then, multiply that result by 200:3.5 / 100 = 0.0350.035 x 200 = 7
