Answer:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Step-by-step explanation:
Answer:
x = 81
Step-by-step explanation:
y = k√x
56 = k√49
56 = k(7)
Divide both sides by 7
8 = k
k = 8
------------------------
When y = 72
72 = 8√x
Divide both sides by 8
9 = √x
Square both sides
81 = x
x = 81
Multiply 5/2 on both sides to clear the fraction.
-8(5/2)=(5/2)(2/5)(k-2)
-20 = k -2
Add 2 to both sides
-18 = k
Answer:
-5/9
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(518×11)−(56×33)=?
Complete the multiplication and the equation becomes
518−1518=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
5−1518=−1018
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 18 using
GCF(10,18) = 2
−10÷218÷2=−59
Therefore:
518−56=−59
Jack left 16.66% of gratuity for the waiter.
Step-by-step explanation:
Given:
Restaurant bill amount = 52.00
Total bill jack paid = 62.40
To find:
percent of gratuity Jack left for the waiter = ?
Solution:
Lets first find the amount jack gave has gratuity to the waiter
The amount given for gratuity = 62.40 - 52.00
The amount given for gratuity = 10.40
Now the percentage is
=
= 
= 16.66 %
