Step-by-step explanation:
I have no clue what to answer 9
Multiplicative inverse is a number which when multiplied with the current number, the answer unit (that is, 1).
Now,
1.725 = 1725/1000 = 69/40
Inverting this and multiplying it with the results yields 1. That is,
69/40*40/69 = 1
Therefore, the multiplicative inverse of 1.725 is 40/69
