Answer:
The least common denominator of the fractions is 24
Step-by-step explanation:
we know that
The <u>least common denominator</u> (LCD) is the smallest number that can be a common denominator for a set of fractions
so
we have
7/8
Multiples of 8 -------> 8,16,24,32,...
5/6
Multiples of 6 -------> 6,12,18,24,...
24 is a common multiple of 6 and 8. It is their lowest common multiple
<em>Alternative Method</em>
we have


The least common multiple are those common and non-common numbers with the greatest exponent
so

Answer:
They will need to hire 5 testers.
Step-by-step explanation:
This question can be solved using a simple rule of three.
For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?
10 developers - 2.5 testers
20 developers - x testes




They will need to hire 5 testers.
Write the scenario as an equation:
25 = 2x -4
Add 4 to each side.
29 = 2x
Solve for x
29/2 = x
Simplify
29/2 = $14.50
Stefon was making $14.50 when he first began mowing.
