Question

⅖-½(7×9) what would that be?

Answer 1

Given the following expression:

`(2)/(5)-(1)/(2)(7x9)`

we can find the product inside the parenthesis first to get the following:

`(2)/(5)-(1)/(2)(7x9)=(2)/(5)-(1)/(2)(63)=(2)/(5)-(63)/(2)`

then, doing the substraction, we get:

`(2)/(5)-(63)/(2)=(4-315)/(10)=-(311)/(10)`

therefore, the simplified expression is -311/10
