Answer:
Depends where the parenthesis are. But if you solve it using PEMDANS it's 1.475.
Step-by-step explanation:
When solving something like this, you use PEMDAS, sometimes known as GEMDAS and solve it in this order.
P/G=Parenthesis
E= Exponents
M= Multiplication
D= Division
A= Addition
S= Subtraction.
So skip P, E, M, and S because there are no parenthesis, exponents, multiplication, or subtraction signs.
So 7/8=0.875. 9/15=0.6, and if you add those you get 1.475
Answer:
This isn't really an answer,but I used to use an app called "Photomath" it shows you the answer as well as the work.
Step-by-step explanation:
I’m thinking A. Would be the most suitable answer for this one
Answer:
To find the sum of a + b where a and b are rational number.
1. when a and b are natural numbers
just add them . for example a =3, b=8
then ,a + b = 11
2. When a and b are whole numbers,
simply add them . for example a= 0, b=8
a+ b = 0 + 8= 8
3. When a and b are integers
for example, a =-1 b=8,
a+ b= -1+ 8 =7,
a=-2, b= -8
a+ b= -2-8=-10
a= -6 , b=2
a+ b= -6 + 2= -4
a= 8, b= -2
a+ b= 8 +(-2) =6
I have written this because Rational number = [Integers{Whole number(Natural number)}]
now when a= Any fraction=
and b = Any fraction=
now ,

Find L.C.M of q and v
= if q and v are Co-prime , just multiply them to find their L.C.M.
For example 14,9. LCM=14×9=126
Otherwise, Find factors of q and v . Then take out common factors first and then multiply the remaining with with common factors.For example
q=12 and v=18
12 =2×2×3
18=2×3×3
common factor =2,3
non common=2,3
L.C.M= 2×2×3×3=36
Suppose LCM of q and v = r
then ,
=
= 
then ,
a + b=
