Explicación paso a paso:

5 1/4 = 5 + 1/4 = (20/4) + (1/4) = 21/4
6 8/9 = 6 + 8/9 = 54/9 + 8/9 = 62/9
Entonces:
(21/4)(62/9) = (21*62)/(4*9) = 1302/36
1302/36 = (1296/36) + (6/36) = 36 + 6/36 = 36 + 1/6
= 36 1/6 metros cuadrados = 36 1/6 m²
La carpa debe medir 36 1/6 m²
2
2 5/8 = 2 + 5/8 = 16/8 + 5/8 = 21/8
la suma de la harina y la sal es de:
21/8 + 1/3 = 63/24 + 8/24 = 71/24
Por regla de tres:
71/24 kg son a 100 bolillos
B kg son a 500 bolillos
B = (500(71/24))/100
B = 5(71/24)
B = 355/24
355/24 = 336/24 + 19/24 = 14 + 19/24 = 14 19/24
Se ocuparan en total:
14 29/24 kg
Si se requiere por ingrediente:
Harina:
(500*21/8)/100 = 5*21/8 = 105/8 = 104/8 + 1/8 = 13 + 1/8 = 13 1/8 kg
Sal:
(500*1/3)/100 = 5*1/3 = 5/3 = 3/3 + 2/3 = 1 + 2/3 = 1 2/3 kg

Se supone que mide de largo 1/7 hm
Entonces el área es de:
(2/5)(1/7) = (2*1)/(5*7) = 2/35 hm²
El terreno tiene un área de:
2/35 hm²
