Greta uses 4 ounces of pasta to make 4/5 of a serving of pasta. how many ounces of pasta are there per serving?

Take 4oz. In a fraction. 4/1. Divide 4/1 by 4/5. When your dividing fractions the divisor ( the second fraction) is flipped.

So then it will be 4/1 multiplied by 5/4 which is 20/4 which is 5. So 5 Oz. Per serving.

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.

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
