What is the multiplicative inverse of 11 7?
The multiplicative inverse means, what do I multiply my number by to get an answer of 1? ex: The multiplicative inverse of 5 is 1/5. 5 * (1/5) = 1 If your number is a fraction to begin with, flip it over. ex: The mult. inverse of 22/7 is 7/22 (22/7)*(7/22) = 1
What is the additive inverse for -n2-7?
-5
What is the inverse -3x plus 5?
To write the inverse, you replace negatives with positives (and vice versa). Thus, for -3x + 5, it would be 3x - 5.
Which real number contains additive inverses for all its elements?
The question is confusing. The additive inverse of a real number is the same number with the sign changed. For example, the additive inverse of -5 is +5 (or simply 5); the additive inverse of 7 (which is the same as +7) is -7.
How do you turn 5 and three sevenths into a multiplicative and a additive inverse?
First convert it into an improper fraction: 5 3/7 becomes 38/7. This is clear because "5" is simply "35/7" (do the math yourself) and 35/7 + 3/7 = 38/7. Additive inverse means "negative." Thus, the "additive inverse" of 38/7 is -38/7. This is true because 38/7 added to -38/7 is 0. That is the definition of an additive inverse. Multiplicative inverse means "reciprocal." Thus, the "multiplicative inverse" of 38/7 is 7/38. This is true because 38/7 multiplied by 7/38 is 266/266, or 1. That is the definition of multiplicative inverse.
