In dividing by 20, we cut off the cipher, and then divided by 2, observing to remove the decimal point one place to the left. We therefore have this RULE. Place the different denominations above each other, so that Ae lowest denomination may stand at the top: commencing at the top, annex ciphers, and divide each denomination by the number expressing how many of such denomination make a unit of the next higher denomination. The last quotient will be the decimal required. Repeat this Rule. EXAMPLES. 1. Reduce 8 5s. 2d. lqi. to the decimal of a % Reduce 3qr. 2na. to the decimal of a yard. OPERATION. 3.
