Write the predecessors of the following numbers:
(a). 94
(b). 10000
(c). 208090
(d). 7654321

Hint: In this given question, we just need to know what a predecessor is and then subtract 1 from the number to get its predecessor as the number.

Complete step-by-step answer:

In this given question, we are asked to find out the predecessors of
(a). 94
(b). 10000
(c). 208090
(d). 7654321
A predecessor of a given number is the previous number of that given number. The way to find it out is subtracting 1 from the given number.
So, the answer is as follows:
(a). The predecessor of 94, as per the statement 1.1 is
94-1=93
(b). The predecessor of 10000, as per the statement 1.1 is
10000-1=9999
(c). The predecessor of 208090, as per the statement 1.1 is
208090-1=208089
(d). The predecessor of 7654321, as per the statement 1.1 is
7654321-1=7654320
So, we have calculated the predecessors of all the given numbers.
Therefore, the predecessors of 94, 10000, 208090 and 7654321 are 93, 9999, 208089 and 7654320 respectively.

Note: In this type of questions, we may also get asked to find the successor of given numbers. A successor is the next number of a given number and can be obtained by adding 1 to it.
