A set of numbers is shown below: {5.4, 6.2, 7.4, 9.2, 15.1}

The number __ from the set will make the equation x + 3 = 8.4 true.

5 is the answer to your question

Step-by-step explanation:

because 5.4+3=8.4

It'll be easiest if you make both fractions have a common denominator

the lowest common multiple of 5 and 6 is 30 so multiply 3/5 by 6 and 1/6 by 5

(3/5)*6 = 18/30          (1/6)*5 = 5/30

now add the two fractions

18/30 + 5/30 = 23/30

this is how much has been eaten. to find what fraction is left, subtract 23/30 from a full box of raisins (30/30 or 1, they mean the same thing)

this gives you 7/30
