| 8/15 * 5/7 = | 40/105 = 8/21 |
| 7/3 + 14/2 + 1/6 = | = 28/12 + 84/12 + 2/12 = 114/2 = 57/1 =57 |
| 5/ 18 ÷ 4/7 = | = 35 / 72 |
| 119 / 8 - 57 / 8 = | = 62 / 8 = 31 / 4 = 7. 75 |
| 3 ⁴ = | 3 * 3 = 9 9 * 9 = 81 3 ⁴ = 81 |
| El perímetro de un cuadrado mide 12 cm , calcula el área. | 12 / 4 = 3 3 * 3 = 9 A = 9 cm ² |
| El lado a del rectángulo mide 15 cm. y el lado b mide 8 cm, calcula el área. | 15 * 8 = 120 A = 120 cm ² |
| En un triángulo equilátero su perímetro corresponde a 27 cm. y su altura a 5 cm, calcula el área. | 27 / 3 = 9 b = 9 9 * 5 = 45 A = 45 cm ² |
| Calcula el perímetro de una estrella de 5 picos con todos sus lados iguales, un lado mide 5cm. | P = 50 cm. |
