Un granjero está cercando su terreno con alambre de púas el terreno tiene forma rectangular y sus medidas son de 37/3m de ancho y 42,8m de largo el número de vueltas fue de 3

He uses 330.8 meters of barbed wire.

Step-by-step explanation:

This can translate to:  

A farmer is fencing his lands with barbed wire. The land is rectangular with 37/3m of width and 42.8m of length, and he puts 3 loops of the wire.

I suppose we want to calculate the amount of wire used.

For each loop, the wire needed is equal to the perimeter of the rectangle, and the perimeter of the rectangle is equal to two times the length plus two times the width.

Then the perimeter is:

P = 2*37/3 m + 2*42.8 m = 110.27 m

And 3 times this amount is:

Wire used = 3*110.27 m = 330.8 m

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
