Question

(21/16 * 12/9) + (- 3/8 * - 12/9) = ?​

Answer 1

`2(1)/(4)`

Explanation:

`((21)/(16) *(12)/(9) )+(-(3)/(8) *-(12)/(9) )`

`(252)/(144)+(36)/(72)`

Before adding these fractions, simplify both fractions.

`(21)/(12) +(3)/(6)`

Still you can simplify.

`(7)/(4) +(1)/(2)`

Now let us add these fractions.

`(7)/(4) +(1)/(2) \\\\(7)/(4) +(1*2)/(2*2) \\\\(7)/(4) +(2)/(4) \\\\(9)/(4) \\\\2(1)/(4)`
