#w=21#

To do these questions, simply cross multiply because it is simply a ratio of expansion or compression.

Starting off with #30/20=w/14#, I can multiply #30# with #14# and divide by #20# to get #w#.

#w = (30xx14)/20#

#w=420/20#

#w=21#

Therefore: #30/20=21/14#

TEST:

#30/20 =1.5#

#21/14=1.5#
