Solutions

1) Add the whole numbers first ( 7 and 2 )

9+7/8+11/12

2) Find the Least Common Denominator (LCD) of

7 / 8,11 / 12

Start by Listing Multiples

List out all multiples of each denominator, and find the first common one.

8 : 8,16,24

12 : 12,24

Therefore, the LCD is 24

Method 2: By Prime Factors

List all prime factors of each denominator, and find the union of these primes.

8 : 2,2,2

12 : 2,2,3

Therefore, the LCD is 2×2×2×3=24

3) Make the denominators the same as the LCD

9+7×3 / 8×3+11×2 / 12×2

4) Simplify. Denominators are now the same

9+21 / 24+22 / 24

5) Join the denominators

9+21+22 / 24
6) Simplify

9+43 / 24

7) Convert 43 / 24 to mixed fraction

9+1 19 / 24

8) Simplify

10 19 / 24

SOLVE PLEASE THANKSS The perimeter of a rectangle is no more than 556 inches. The length is 150 inches. Write an inequality and

hoa [83]

So perimeter<556
permiter=2Legnth+2Width
so perimiter=2(legnth+width)

556/2>Legnth+width
228>legnth +width
legnth =150
so 228>150+width
subtract 150 from both sides
78>width
width cand be 78 or less but not 0 or negative

anoth way to do it is 556>2(150)+2width
556>300+2width
subtract 300 from both sides
256>2width
divide both sides by 2
78>width
