Whats 1 and 2/3 + 1 and 5/6​
Dima020 [189]
1 2/3 + 1 5/6

We’ll start by converting the 2/3 to 6ths so we have a common denominator.

Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.

So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.

Let me know where you have questions.

Sindrei [870]

Yo sup??

Lenght of two side will be equal to 20 in as its an isoceles triangle.

The third side will be

x^2=b^2+h^2    (by pythagoreas theorem)

x=9√2 in

Therefore the perimeter is = 9+9+9√2

=9√2(√2+1) in
