What is 16/10 as a mixed number simplified if possible ??
ozzi
16/10 as a mixed number would be {1 6/10} or {1 3/5}. First, you figure out how many times the denominator fits into the numerator. So you see how many times ten fits into 16 (the answer would be 1) and that's your whole number. Then, you subtract the denominator from the numerator (16-10) and put our answer (5) as the numerator in the fraction next to the 1 you got in the beginning. Then, all you have to do is simplify.

EXAMPLE:

18/10
how many times does 10 go into 18? once.

The surface area of the triangular prism is 1664 square yards.

Explanation:

Given that a triangular prism is 20 yards long and has a triangular face with a base of 24 yards and a height of 16 yards . the other two sides of the triangle are each 20 yards.

<u>Surface area of the triangular prism:</u>

The formula to determine the surface area of the triangular prism is

SA=bh+Pl

where base b=24 ,

height h=16,

length l=20 and

Perimeter P=20+20+24=64

Substituting these values in the above formula, we get,

SA=(24\times 16)+(64\times 20)

     =384+1280

SA=1664

Thus, the surface area of the triangular prism is 1664 square yards.
