Answer 1

Hola!

Antes de resolver, 2 errores que tienes allí :

• 80 × 5 - 100 = 300

• 3405 - 3000 = 405

Ahora resolvemos ↓

• 7.8 - 1.2 = 6.6

• 19.7 - 1.3 = 18.4

• 100 ÷ 10 = 10

• 250 ÷ 50 = 5

• 1/2 + 2/2 = 3/2

• 3/7 - 1/7 = 2/7

• 3/5 + 2/10 = 4/5

• 3/4 - 1/8 = 5/8

• 3/4 × 5/6 = 5/8

• 4/7 × 3/8 = 3/14

Saludos y buenas noches.
