coldgirl [10]

Answer:

The least common denominator of the fractions is 24

Step-by-step explanation:

we know that

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

$8=2^{3}$

$6=2*3$

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

$lcm= 2^{3}*3=24$

Two families go to a shake shack. The Johnsons order four fires and six cheeseburgers for $52. The Liauttads order three fries a

stira [4]

4 fries + 6 cheeseburgers = $52

3 fries + 2 cheeseburgers = $24

9 fries + 6 cheeseburgers = $24×3

= $72

$72-$52=$20

5 fries = $20

1 fries = $20÷5

= $4

1 cheeseburger = [$24 - (3×$4)]÷2

= $6
