1/2 - 2/9 = 5/18
Two thirds is six ninths; six ninths minus four ninths is two ninths.
7 2/9 - 4 5/8 Step one , bring to improper(top heavy) fractions. 65/9 - 37/8 Step two bring to a common denominator (9 x 8 = 72) in this case, and equivalent numerators. Hence [65(8) - 37(9)] / 72 Step 3 Multiply out the curved brackets. [520 - 333 ] / 72 Step 4 subtract the numerators 187/72 Step 5 Reduced to a mixed number. 2 43/72 The answer!!!!! NB This fraction will NOT reduce any further as '43' is a prime number'. NNB Looking at the original coefficients of '7' & '4', when subtract make '3'. However, allowing for the fractional component, then '2' is a correct coefficient. Hope that helps!!!!!!
