Question

Noam solved the equation for k using the following calculations
K-7.6=10.35
+7.6. +7.6
K=17.41
What error did he make?

Answer 1

The mistake here was the .6 was treated as .06. Adding 7.6 to 10.35 really gives 17.95.

Answer 2

Answer:

The real answer is that he made an error adding 10.35 and 7.6.

Step-by-step explanation:

If you do the math adding again, 10.35 + 7.6 would be 17.95.

10 + 7  = 17

0.35 + 0.6 = 0.95

17 + 9.5 = 17.95
