If a company made 2.3 million this year, and that is 4.1 million less than last year, how much did they make last year

6.4 million

Step-by-step explanation:

Let the amount made last year be represented by Z.

2.3M = Z - 4.1M

Z = 2.3M + 4.1M

Z = 6.4M

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
