<span>We need to find the value of 4 in the given number which is 745:
To be able to get the value of 4, we need to get familiar to each digit’s place
value.</span>
<span>=> Let us give the value of each digit first.
=> 5 = placed in one’s value
=> 4 = placed in tens value
=> 7 = placed in hundreds value
Thus,
=> 745 = 700 + 40 + 5
Therefore the value of 4 in 745 is tens or 40.
