Answer :
42 is 30% of 140
This is evident because, 42÷140=0.3
And you should hopefully know your place values right?
So then we know that 3 is in the10ths place and so to change the decimal to a fraction we get 3/10 which then changed to a percent, is equal to 30.
Long story short, 42 is 30% of 140 :)
