Question

Daniel writes 0.4 <0.13 "because 4 is less than 13." Ex-

plain the correct reasoning
a) by drawing hundredths charts,
b) by a number line picture, and
c) by converting to fractions.
d) For which of your explanations does it help to write
0.4 as 0.40?​

Answer 1

I would do C). Because .4 converted into a fraction would be 2/5 and .13 converted would be 13/100. So if u multiply the first fraction by 20 (to make the two have the same denominator) it would be 40/100 which shows that .4 is not less then .13. I think u still need to do all other parts, but hope this helped.
