Answer: use the keep change flip method
1. kep the first fraction
2.then change the division symbol to a x and then flip ur second fraction
3. then cross multiply , then simplify ur answer (if neeeded)
Step-by-step explanation:
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=
Answer:
$56.
Step-by-step explanation:
Given : $23.45+$3.98+$16.66+$12.08
To Find : Estimate to the nearest dollar , the total cost
Solution:
Total cost = $23.45+$3.98+$16.66+$12.08
Total cost = $56.17
So, The total cost = 56.17
Find the place value you want to round off and look to the digit just to the right of it.
If that digit is less than 5, do not change the "rounding digit"
If that digit is greater than or equal to 5, add one to the rounding digit and change all digits to the right of the rounding digit to zero.
So, Now The total cost to nearest dollar is $56.
