Answer:

7.5

Step-by-step explanation:

One way in which you could do this problem would be to write and solve an equation of ratios:


100%          15

---------  = ----------

 50%            x

Cross multipying results in 100x = 750, so that x = 7.5.

50% of the number is 7.5.

Answer:

The answer is 7.5.

Step-by-step explanation:

Since we're looking for half of 15, divide 15 by 2 (or multiply 15 by 0.5, it's the same thing) and you get 7.5.


I hope this helped! :)

MariettaO [177]
W - 2.76 = 6.7

isolate the W by adding 2.76 to both sides of the equal sign

W - 2.76 (+2.76) = 6.7 (+2.76)

W = 6.7 + 2.76

W = 9.46

9.46 is your answer
