if you have 12 pr's, and you take 3 away... you're left with 9 pr's....
12pr + 2st - 3pr -8rs
9pr +2st - 8rs

6.53 + 1.4 / (0.7 + 0.1). ( / - this is a division sign just incase you dont know)

Answers

aright i figured it out:)
step one we need to remember PEMDAS
P :  (parentheses)
E : exponents ³
M : multiplication x 
D : division ÷
A : addition +
S : subtraction - 
i always remembered this by using this one sentence 
"P"lease "E"xcuse "M"y "D"ear "A"unt "S"ally
but that's a different topic;) lets solve our problem 
6.53 + 1.4 ÷ (0.7 + 0.1)
well lets follow along with out PEMDAS and first i see parentheses as our first step. So lets solve what we have within our Parentheses. 
0.7 + 0.1 = 0.8 now lets plug in what we have 
6.53 + 1.4 ÷ 0.8  now i see another step we can do here and thats division
1.4 ÷ 0.8 = 1.75 now lets plug in what we finally have 
6.53 + 1.75 = 8.28
answer? 8.28
if this was helpful
then don't forget too
MARK ME BRAINLIEST! :D
6.53+1.4/(0.7+0.1)=6.53 + 1.4/.8=6.53 + 1.75=8.28

Answer: 6.53+1.4/(0.7+0.1)=8.28
