Answer:
42/90
Step-by-step explanation:
<u> </u>
Let x = .46
multiply both sides by 10
<u> </u>
10x = 4.66
multiply both sides by 10 again
<u> </u>
100x = 46.66
<u> </u> <u> </u>
100x - 10x = 46.66 - 4.66
90x = 42
x = 42 / 90
Can be reduced to x = 21/45
First multiply 4 so x is on its own.
5/9 multiplied by 4/1 is 20/9.
20/9 simplifies to 2 and 2/9.
x = 2 and 2/9
