( „/” = supra )

a) 1/10+3/1000
b) 3/10+7/2
c)4/15+1/20
d)6/25+7/20
e)11/14+3/35
f)1/8+7/12
g)5/33+1/22

EXEMPLU:(poza) punctul f​

Answer 1

Răspuns:

1/10 + 3/1000 = 100/1000 + 3/1000 = 103/1000

3/10 + 7/2 = 3/10 + 35/10 = 38/10 =3.8

4/15+1/20=16/60+3/60=19/60

6/25+7/20=24/100+35/100=59/100

Explicație pas cu pas:

restu nu mai fac ca e usor

trb sa aduci la acelasi numitor(numarul de jos)

dupa aduni numerele de sus si gata

♡Bună!!!Sper ca te-am ajutat!Spor la teme!♡

a)1/10+3/1000=1/10amplificat cu 100+3/1000=100/1000+3/1000=103/1000

b)3/10+7/2=3/10+7/2amplificat cu 5=3/10+35/10=38/10simplificat cu 2=19/5

c)4/15+1/20=4/15amplificat cu 4+1/20amplificat cu 3=16/60+3/60=19/60

d)6/25+7/20=6/25amplificat cu 4+7/20amplificat cu 5=24/100+20/100=44/100simplificat cu 2=22/50

e)11/14+3/35=11/14amplificat cu 5+3/35amplificat cu 2=55/70+6/70=61/70

g)5/33+1/22=5/33amplificat cu 2+1/22amplificat cu 3=10/66+3/66=13/66
