To order these sets of numbers, we first need to convert the numbers into the same form such as all decimals or all fractions or all percentages.
Right now I'll be converting it into fractions.

0.7 can be written as 7/10, because 1 (ie. 10/10) is ten 0.1s
Now we have seven 0.1s so it is 7/10

85% can be converted into 85/100, or to be uniform as the last one is 8.5/10.
This is because 1 = 100% = 100/100
So 85% can be written as 85/100 or 8.5/10 (note that this is not a correct way to write decimals in fractions but it can make this q easier)

At last 4/5 can be expanded to 8/10, just to make the denominator the same)
Just multiply both numbers in the fraction by 2 as 5 x 2 is 10.

So now we have the answer.
From smallest to largest,
0.7 < 4/5 < 85%
