What is 3.4 / x = 2.17/ 7.7?

Mathematics

adoni [48]3 years ago

You could use a method called cross products to solve this proportional equation.  What you would do is multiply 3.4*7.7 =2.17*x

If multiplied correctly, your equation should be 26.18 = 2.17x

You are trying to get the variable alone on one side.  To do this, you have to undo the multiplication of the coefficient.  The opposite of multiplication is division, so you would divide both sides by 2.17.

If done correctly, your equation should now be x=<span>12.064516129

However, this can be rounded to x= approximately 12.066

I need help with this problem bk I’m so konfused by it
soldi70 [24.7K]

Do you want 5 and 6 or just 5? 5 is kind of neat.

44.5% = 0.445

4/9 = 0.4444444

You have enough information to put the numbers in order.

0.44 is the smallest number.

0.44444444.... is the next smallest number

0.4445 is bigger than the number above. 5 is in the ten thousandths place. that is bigger than 4 in the thousands place of 4/9

Finally the largest number of all is 0.445 for the same reason given above.

Six

5/12 = 0.416666

0.4

42% = 42/100 = 0.42

0.416

0.4 is the smallest number

0.416 is the next smallest number

0.41666666 is bigger than 0.416 because you are adding a bunch of 6s onto the decimal place.

The largest one is 0.42. You can put these into your calculator to verify the results. For example, 0.42 - 0.4166666 = 0.003344. Any result more than 0 will show that the first number is bigger than the second.
