$$\frac{\color{#007DDC}{b}}{\color{#9a00c7}{c}}=\color{#00880A}{Q}\frac{\color{#e65021}{R}}{\color{#9a00c7}{c}}$$`(``b``-:``c``)=``Q` and `R` is the remainderAccording to BODMAS, Bracket is prioritized over Multiplication, then followed by Addition.Ignore the other operations for now and only do the operation inside the bracket, which is subtraction.$$\color{#9E9E9E}{\frac{3}{4}\times\frac{2}{3}+}\color{#00880A}{\left({3-\frac{2}{3}}\right)}$$ First, make `3` into a fraction. Recall that all whole numbers has `1` as a denominator`3` `=` `3/1` To proceed with Subtraction, find the `LCD` of `1` and `3`Multiples of `1`:$$1\;\;2\;\;\color{#004ec4}{3}\;\;4\;\;5$$Multiples of `3`:$$\color{#004ec4}{3}\;\;6\;\;9\;\;12\;\;15$$The `LCD` of `1` and `3` is `3`Use the `LCD` as the denominator and then subtract.`3/1-2/3` `=` $$\frac{(\color{#004ec4}{3}\div1)\times3}{\color{#004ec4}{3}}-\frac{(\color{#004ec4}{3}\div3)\times2}{\color{#004ec4}{3}}$$ `=` `(3xx3)/3-(1xx2)/3` `=` `9/2-2/3` `=` `7/3` Next, ignore the addition for now and only do Multiplication.$$\color{#CC0000}{\frac{3}{4}\times\frac{2}{3}}\color{#9E9E9E}{+\frac{7}{3}}$$ `=` $$\frac{6}{12}\color{#9E9E9E}{+\frac{7}{3}}$$ `=` $$\frac{1}{2}\color{#9E9E9E}{+\frac{7}{3}}$$ Simplify` Next, to proceed with Addition, find the `LCD` of `2` and `3`Multiples of `2`:$$2\;\;4\;\;\color{#004ec4}{6}\;\;8\;\;10$$Multiples of `3`:$$3\;\;\color{#004ec4}{6}\;\;9\;\;12\;\;15$$The `LCD` of `2` and `3` is `6`Use the `LCD` as the denominator and then add.`1/2+7/3` `=` $$\frac{(\color{#004ec4}{6}\div2)\times1}{\color{#004ec4}{6}}+\frac{(\color{#004ec4}{6}\div3)\times7}{\color{#004ec4}{6}}$$ `=` `(3xx1)/6+(2xx7)/6` `=` `3/6+14/6` `=` `17/6` Finally, convert the improper fraction into a mixed number.Arrange the numbers for long division
`6` goes into `17` two times. So write `2` above the line.
Multiply `2` to `6` and write the answer below `17`
Subtract `12` from `17` and write the answer one line below
Since `6` cannot go into `5` anymore, `5` is left as the Remainder and `2` is the QuotientSubstitute values into the given formula$$\frac{\color{#007DDC}{b}}{\color{#9a00c7}{c}}$$ `=` $$\color{#00880A}{Q}\frac{\color{#e65021}{R}}{\color{#9a00c7}{c}}$$ $$\frac{\color{#007DDC}{17}}{\color{#9a00c7}{6}}$$ `=` $$\color{#00880A}{2}\frac{\color{#e65021}{5}}{\color{#9a00c7}{6}}$$ `2 5/6` -

`8` goes into `14` one time. So write `1` above the line.
Multiply `1` to `8` and write the answer below `14`
Subtract `8` from `14` and write the answer one line below
Since `8` cannot go into `6` anymore, `6` is left as the Remainder and `1` is the QuotientSubstitute values into the given formula$$\frac{\color{#007DDC}{b}}{\color{#9a00c7}{c}}$$ `=` $$\color{#00880A}{Q}\frac{\color{#e65021}{R}}{\color{#9a00c7}{c}}$$ $$\frac{\color{#007DDC}{14}}{\color{#9a00c7}{8}}$$ `=` $$\color{#00880A}{1}\frac{\color{#e65021}{6}}{\color{#9a00c7}{8}}$$ `=` `1 3/4` Simplify the fraction `1 3/4`
