What is Newton's number? My number divided by. 1 is 23 less than 57

3.4

Step-by-step explanation:

my number divided by 0.1 is 23 less then 57 ...

let n represent the number

n / 0.1 = 57 - 23

n / 0.1 = 34 ... multiply both sides by 0.1, cancelling it on the left side

n = 34 * 0.1

n = 3.4 <===
