Question

Help fast with the ones that are circled

Answer 1

Answer:

6. B) 0.23

7. B) 14

Step-by-step explanation:

6. To solve, change the fractions into decimals. To do so, try to get them to = 100, and then move the decimal point to the left two place values:

1/5 = 20/100 = 0.20

1/4 = 25/100 = 0.25

You are trying to find a decimal point that is in between these two decimals. In this case, your answers can be the following:

0.21, 0.22, 0.23, 0.24

B) 0.23 is your answer.

7. To solve, combine the ones that have already chosen, and subtract from the total. Find common denominators:

(1/3) + (1/5) = (5/15) + (3/15) = 8/15 x (2/2) = 16/30

16 of the students chose either station K or L.

There are 30 students in all. Subtract 16 from 30:

30 - 16 = 14

14 students chose station M

B) 14 is your answer.
