turn each number into an improper fraction

27 1/2 = (2*27+1 )/2  = 55/2

2 1/4 = (4*2+1)/4  = 9/4

55/2 divided by 9/4

copy dot flip

55/2 * 4/9

220/18

110/9                                       12*9 = 108

12    2/9  weeks

or if we round   13 weeks

Evaluate each expression <br><br> 10 (e+7)<br> E=3
Nostrana [21]
Plug in e for 3.

10(3+7)

Use the distributive property. a(b+c)= ab+ac

10*3= 30, 10*7=70

30+70=100

The expression equals 100.

I hope this helps!
