Question

11 Calculează: #a) 100 : 20 + 100: 2 #b) 100 : (8 × 2 +3*3) = e) 100 = 2 × (15 +30) #d) (100 =2) × (36: 15)​

Answer 1

Răspuns:

Explicație pas cu pas:

a) 100 : 20 + 100: 2 = 5 + 50 = 55

#b) 100 : (8 × 2 +3*3) = 100 : (16 + 9) = 100 : 25 = 4

e) 100 : 2 × (15 +30) = 100 : 2 × 45 = 50 × 45 = 2250

#d) (100 : 2) × (36: 15)​ = 50 × 2,4 = 120

Answer 2

Răspuns:

Explicație pas cu pas:

a) 100 : 20 + 100: 2=5+50=55

b) 100 : (8 × 2 +3*3) =100:(16+9)=100:25=4

e) 100 :2 × (15 +30)=100:2·45=50·45=2250

d) (100:2) × (36: 15)​=50·12/5=120
