Contact [7]

Answer:

\dfrac{15}{2}

Step-by-step explanation:

Mumz [18]

2 1/24

Rewriting our equation with parts separated

2/3+1+3/8

Solving the fraction parts

2/3+3/8=?

Find the LCD of 2/3 and 3/8 and rewrite to solve with the equivalent fractions.

LCD = 24

16/24+9/24=25/24

Simplifying the fraction part, 25/24,

25/24=1 1/24

Combining the whole and fraction parts

1+1+1/24=2 1/24

LuckyWell [14K]

Answer:

17.16

Step-by-step explanation:

So if the area of the rectangle is 8.8*3.9=34.32, L*W=H, then the triangle which has the same length and width, would have L*W*1/2. If you fill in the variables, then you would get 8.8*3.9*1/2=17.16. You can do this on any calculator, and please put my answer as the brainliest.✌
