Answer 1

Hazel Anglin

#-9/20#

We can consider this to be the multiplication of 3 fractions.

#"That is "#

#1/4xx(-9)/1xx1/5#

#"there is no "color(blue)"cancelling" " between numerator/denominator"#

#"Hence multiply remaining values on numerator/denominator"#

#rArr(1xx-9xx1)/(4xx1xx5)#

#=(-9)/20#

#=-9/20larrcolor(red)" in simplest form"#
