Question

I forgot how to do this​

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{1}}}}}`

Explanation:

`\sf{ (1)/(2) * 2}`

Multiply the numerators for the numerator and multiply the denominators for its denominator and reduce the fraction obtained after multiplication into lowest term.

`\dashrightarrow{ \sf{ (1 * 2)/(2 * 1) }}`

`\dashrightarrow{ \sf{ (2)/(2) }}`

`\dashrightarrow{ \sf{1}}`

Or, You can simply reduce the fraction with 2, which results to 1.

Hope I helped!

Best regards! :D
