Han subtracts 52 from 55. How do you know that these numbers represent tenths?

It’s not really an answer

Step-by-step explanation:

I think when you’re doing the problem the 55 was originally only a five,

because you bring the five down and make it 55 then subtract 55 and 52 which would give you 3 and after that bring down the 9 in 31.59 and make it 39 the see how many times 13 goes Into 39 from the problem 39÷ 31.59 and that would be 3 times  and then subtract 39-39 which would be zero and you would be done

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
