6: 11 and 42: 88 was the equivalent ratio

False

Note what is being multiplied to both numerator and denominator.

6 is multiplied by 7 to get 42, and 11 is multiplied by 8 to get 88

Note that in a ratio, however, you have to multiply (or divide, however you want to look at it) the same amount to both numerator and denominator.
