The answer is 9/16 because you have to divide the two fractions <span />
If you would like to know how much did the shirt cost after 6% tax, you can calculate this using the following steps:
6% of $43 = 6/100 * 43 = $2.58
$43 + $2.58 = $45.58
The correct result would be $45.58.
6.8 - 4.2b = 5.6b - 3 (subtract 6.8 from each side)
- 4.2b = 5.6b - 3 - 6.8
- 4.2b = 5.6b - 9.8 (subtract 5.8b from each side)
- 4.2b - 5.6b = - 9.8
- 9.8b = -9.8 (divide - 9.8 from each side)
b = -9.8/-9.8
b = 1
The answer is 1
