If I understand the problem correctly you need to convert the fraction into a decimal or the decimal into a fraction. Let's convert 6 and 2 fifths into a decimal by dividing 2 by 5

We get

6.4 - y = 6.4

Then get y alone by subtracting 6.4 from both sides.

-y = 0

Then you  multiply both sides by (- ) and you get y = 0 because anything times 0 = 0

your answer is y=0

Solve :-

6.4 - y = 62 /5

By simple cross multiplication method :-

6.4 x 5 - y = 62

32 - y = 62

- y = 62 - 32

- y = 30

y = -30( answer)
answered Oct 5, 2012 by Jessica_Ruby Level 3 User (3,980 points)
TO SOLVE FOR y ,you transpose 6.4 to the right to make it -6.4.that is

-y = 6 2/5 -6.4 that is

-y = 6.4 -6.4

so -y = 0 you divide -1 both side to make the value y into positive so that is

-y/-1 = 0/-1

so the answer is

y= 0 it is only zero because theres no number that has negative zero>..................................thats all
answered Oct 8, 2012 by anonymous
6.4 - y = 6 2

6.4 - 6 2/6 = y

y = 6.4 - 6 2/5

at this point you can convert decimals to fractions or fractions to decimals

6.4 = 6 4/10 = 6 2/5

so:

y = 6 2/5 - 6 2/5 = 0,     SO: Y = 0

You try converting fractions to decimals, and solve the problem.

6.4 - y = 6 2/5
We need to convert both the numbers to the same unit, either both of them be fractions, or both of them be decimals. You can solve it either way, i've solved it by converting both the numbers to decimal.
6.4 - y = 6 (2/5) 2
6.4 - y = 6 4/10
6.4 - y = 6.4
y = 6.4 - 6.4
y = 0
answered Oct 12, 2012 by anonymous
First yo do multiplication. Get a calculator and do 62/5=? 12.4

Then you try to get the y alone so you minus the 6.4. So your work should look like this:

y = 12.4-6.4

Now do 12.4-6.4=? 6

So your answer should be:

y = 6

6.4 - y = 6 2/5

6.4 = y + 6 2/5

6.4 = y + 6.4

6.4 - 6.4 = y

y=0
answered Oct 17, 2012 by anonymous

6.4-y=6 2/5 so 6 2/5=6.4 so 6.4-y=6.4 that makes y=0

answered Oct 18, 2012 by anonymous
Solve :-

6.4 - y = 62 / 5

By simple cross multiplication method :-

32.0 - 5 y = 62

-5 y = 62 + 32

- 5 y = 94

-y = 94 / 5

- y = 18.8

y = - 18.8 (answer)

6.4 - 6 2/5 = y  * step1;

6.4 - 6.4 = y     * step2;

0 = y * step3;

Q: 6.4 - y = 62/5 -----------> (1)

y = ?

Soln:

Multiply both sides of eq (1) by 5, we get:

5(6.4) - 5y = 62

=> 32 - 5y = 62

=> -5y = 62 - 32

=> -5y = 30 --------------------->(2)

now, by dividing both sides of eq (2) by -5, we get:

y = -6  {ANS}
