2/13 × 26 2/5 = ??

To do this, we have to take the second fraction, and turn it into a mixed number.

To do so, we have to multiply the denominator (bottom number) with the whole number, and then add that with the numerator (top number).

26 2/5= (5 × 26) + 2 = (130) + 2 = 132/5

Now, we do 2/13 × 132/5

Multiply the top numbers together, and then multiply the bottom numbers together.

Now, you have 264/65

You have to make this a mixed number, by seeing how many times (64) goes into (264).

(64) goes into 264 four times, with a remainder of 4, so now, your answer is: 

4 4/65

2/13 * 26 2/5
2/13 * 132/5
2 * 132= 264
13 * 5= 65
264/65  = 4  4/65

3.5 m
marysya [2.9K]

Answer:

This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.

Now, the circunference of a circle can be written as:

C = 2*pi*r

where:

pi = 3.14

r = radius = half of the diameter = 3.5m/2 = 1.75m

Then replacing those values in the equation for the circumference we have:

C = 2*3.14*1.75m = 10.99 m.

And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)

We can safely round up the circumference to the next whole number, C = 11m
