Arianna solved a fraction division problem using the rule "multiply by the reciprocal." her work is shown below. two-thirds divided by startfraction 4 over 5 endfraction. two-thirds times startfraction 4 over 5 endfraction = startfraction 8 over 15 endfraction which is the most accurate description of arianna's work? arianna solved the problem correctly. arianna multiplied the dividend by the divisor instead of finding the reciprocal. arianna multiplied the denominators instead of finding a common denominator. arianna multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.

Arianna multiplied the dividend by the divisor instead of finding the reciprocal.

Step-by-step explanation:

The fraction division problem Arianna solved is

Adrianna's next step is  

We are supposed to choose from the options the most accurate description of Arianna's work.

The mistake Arianna committed is that, she did not reciprocate the before multiplying.

Therefore the correct answer is:

Arianna multiplied the dividend by the divisor instead of finding the reciprocal.

answer: 12

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
