Answer:

#126#

Explanation:

Write the maths exactly as it sounds,

A percent is a value out of #100#

Find #60%""# of #210#
#color(white)(xxx)darr" "darr""darr#
#" "60/100" "xx 210#

#=126#

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can do this mentally by realising that #60% = 50%+10%#

#50% xx 210 = 1/2 xx 210 = 105#

#10% xx 210 = 210div 10 = 21#

#105+21 = 126#
