Answer:
14:21
Step-by-step explanation:
Think of it as equal fractions, if that helps.
Finding an equivalent fraction is the same as finding an equivalent ratio.
If you multiply both the numerator and denominator of 2/3 or 2:3 by the same number, you'd get an equivalent fraction/ratio.
2 multiplied by 7 is 14, 3 multiplied by 7 is 21. So, 2:3 and 14:21 are equivalent.
