Multiply fractions by a whole numbers

1/3 x 3 = 1

Step-by-step explanation:

This is because when you multiply fractions by a whole number the whole number is going to go over one. So in the example I put you would 1/3 x 3/1 =1. Now with fractions when have the same number as the numerator and denominator you can get one.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p
