If three tenths of the bowling pins were up, what fraction of the bowling pins would be down?

There would be seven tenths of the bowling pins down

Step-by-step explanation:

Lets say that there are 10 bowling pins in all. All would be represented in the fraction 10/10. If 3/10 of the bowling pins are up (which means that 3 bowling pins are up), you can just subtract the number of all the bowling pins to get the number of bowling pins down, which, in this case, would be 7/10 or 7 bowling pins. If you subtract 10/10 - 3/10, then you get 7/10, which is the number (fraction) of the bowling pins that are down.
