Question

Solve the following with steps
5/10 * -4/12 - 1/3 - 4/12 * 2/10

Answer 1

Explanation:

`(5)/(10)*(-4)/(12)-(1)/(3)-(4)/(12)*(2)/(10)\\\\=(1)/(2)*(-1)/(3)-(1)/(3)-(1)/(3)*(1)/(5)\\\\= (-1)/(3)[(1)/(2)+1+(1)/(5)]\\\\=(-1)/(3)[(1*5)/(2*5)]+(1*10)/(1*10)+(1*2)/(5*2)]\\\\=(-1)/(3)[(5)/(10)+(10)/(10)+(2)/(10)]\\\\=(-1)/(3)[(5+10+2)/(10)]\\\\=(-1)/(3)*(17)/(10)\\\\=(-17)/(30)`
