find 3/4+(-5/2)+(-8/3)+5/5
Answers
Answer:
41/12 i think
Step-by-step explanation:
find a common denominator in 3/4 and 5/5 which is 20
mulitply both sides so the denominator can be 20
3/4 = 15/20 ; 5/5 = 20/20
add them; 35/20
do the same for -5/2 and -8/3
-5/2 = -15/6 ; -8/3 = -16/6
= -31/6
find the common denominator in -31/6 and 35/20 which is 60
-31/10 = -310/60 ; 35/20 = 105/60
add; -205/60
then simplify for 41/12
Step-by-step explanation:
DMAS - DIVISION, MULTIPLICATION, ADDITION AND SUBTRACTION
SO WE MUST DO THE ADDITION PART FIRST
3/4 + 5/5
COMMON DENOMINATOR = 20
3/4×5/5 = 15/20
5/5×4/4 = 20/20
SO NOW WE HAVE EQUAL DENOMINATOR FOR BOTH, WE CAN ADD THEM
15/20 + 20/20
= 35/20
=7/4
NOW THE SUBTRACTION PART
(-5/2)+(-8/3)
COMMON DENOMINATOR = 6
-5/2×3/3 = -15/6
-8/3×2/2 = -16/6
NOW WE HAVE EQUAL DENOMINATOR
-15/6 -16/6
= -31/6
NOW THE LAST PART
7/4+(-31/6)
COMMON DENOMINATOR = 24
7/4×6/6 = 42/24
-31/6×4/4 = -124/24
NOW WE HAVE EQUAL DENOMINATOR
-124/24+42/24
= -82/24
= -41/12
