Can you help me identfity the additive and muliplicative inverse for the following numbers?-10-0.1254/3How do you find the answer?
Additive inverse : what number adds to it to make 0 (i.e multiply it by -1) Multupicative inverse : what number multiplies to it to make 1 (i.e. find the reciprocal
Additive inverses for numbers are nothing other than change the sign (make a + into a -, or a - into a +), you could also multiply by -1 to achieve the same goal. So the additive inverses for each are +10 +0.125 -4/3 The multiplicative inverse is the reciprocal, which means exchange numerator and denominator of an integer fraction. If it is not written as a integer fraction do so, or divide it by 1. So first rewriting your list as integer fractions -10/1 -0.125 = -1/8 4/3 (didn't change it was already an integer fraction) the multiplicative inverses are -1/10 -8/1 = -8 3/4 Notice for the multiplicative inverse you DO NOT change the sign.
additive inv: 1. +10 2. +0.125 3. -4/3 mult. inv: 1. -1/10 2. -8 3. 3/4
a multiplicative inverse for a number x, denoted by 1?x , is a number which when multiplied by x yields the multiplicative identity, 1 1/-10 1/-0.125=-8 1/(4/3)=3/4 the additive inverse, or opposite, of a number n is the number that, when added to n, yields zero. 10 0.125 -4/3
