#4 1/4xx8=34#

Explanation:

Another way to work out the answer:

Given:

#4 1/4xx8#

Convert #color(red)4 color(green)1/color(blue)4# to an improper fraction by multiplying the #color(blue)"denominator"# by the #color(red)"whole number"#, then adding the #color(green)"numerator"#, and putting the result over the same #color(blue)"denominator"#.

#color(red)a color(green)b/color(blue)c=((color(blue)cxxcolor(red)a+color(green)b))/color(blue)c#

#((color(blue)4xxcolor(red)4+color(green)1))/color(blue)4=17/4#

Multiply #17/4# by #8#.

#17/4xx8#

Simplify.

#136/4#
