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
6.4-y=6 2/5 so 6 2/5=6.4 so 6.4-y=6.4 that makes y=0
What are the solutions of ? Write the solutions as either the union or the intersection of two sets.
Estimate the fraction:
A B C D
0---------•---•---------•---•---------1
can u explain it better?
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}
