Write the predecessor of:

(a) 94 (b) 10000


(c) 208090 (d) 7654321

The predeccessor of a number is the number obtained by substracting one from the given number, also known as the before number.


For example – predecessor of 9 will be 8 (9-1 = 8)


(a) 94 – 1 = 93


(b) 10000 – 1 = 9999


(c) 208090 – 1 = 208089


(d) 7654321 – 1 = 7654320
