<span>8 21/40

You can either solve this by dividing 21/40 and then adding 8 to it.
21/40 = 0.525
0.525 + 8 = 8.525

Another way is to change it into an improper fraction. This is done by multiplying the denominator (40) by the whole number (8) then adding that to the numerator (21). That number then becomes the numerator, but make to keep the denominator the same (40).
40 </span>× 8 = 320
320 + 21 = 341
8 21/40 = 341/40
Then input 341/40 into a calculator or do long/short division.
341/40 = 8.525

Either way, the answer will be 8.525.

Hey, there !

If you want to know it as a "improper fraction" , you can

Multiply the denominator from the front number
Whatever the denominator and front number is , you add it to the numerator

So, for this problem we first have the multiply the front number from the denominator

Like: 8 (40)
That gives us the answer of: 320

Now we have to add 320 to 21

Like: 320 + 21

That gives us the answer of:341

We keep our denominator (which is "40" )

Your improper fraction would be:

341 / 40

Good luck on your assignment and enjoy your day!

The surface area of a rectangular prism is always:

A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.

A=2(50*90+50*3.5+90*3.5)

A=2(4500+175+315)

A=2(4990)

A=9980 mm^2
