Question

Simone wrote that 2 + 5.8 = 6.

Use the drop-down menus to explain why 6 is incorrect.

Answer 1

7.8

0.2

Explanation:

2 is in the ones place, to get to six you need the value of 2 in the tenths place (0.2)

2+5.8 is 7.8 (add the ones places together to get 7)

0.2+5.8=6 (add in the tenths place)
