#44#

#325/100 = 143/x#

#(325/100)x = 143(x/x)#

#325x100/100 =143*100#

#325x = 14300#

#325x/325 =14300/325#

#x = 44#

#x = 44#

We are told that #325%# of some number gives #143#

(This means more than 3 times the number...)

Use #x# as the unknown number and write an equation.

#325/100 xx x = 143" "larr# isolate #x#

#x =143 xx 100/325#

#x = 44#
