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!!!!!!
