Answer:
<
<
>
Explanation:
the closed point of the < > symbol should point to the smallest number
Decimal points work in a way that means if a decimal is 0.2 is larger than 0.19
this is because the further away from the decimal point the smaller the unit is
so the 2 in 0.2 is 2 tenths
so in your question
0.15 is one tenth and 5 hundredths
its like 15 the digit further to the right is larger and you can add as many zeros after and it will have the same value
while 0.8 is 8 tenths and 0 hundredths
so its like 80 is larger than 15
if you need help with the rest let me know but this should help enough to figure out the rest
top answer is <
second is <
last is >
a hundredth is 10 times smaller than a tenth and a thousandth is 10 times smaller than a hundredth
