Verifica egalitatile verificând calculele

a) 2×(268+147)-49÷7= 56÷7+3×(104+195)

b) 155÷5+6×(159+78)= 7×(29+112)-144÷12

c) 4×(109+125)-110÷20=2×(199+269)-88÷8

Mă puteți ajuta sa calculez?

Pls

Răspuns :

a)2*(268+147)-49:7=56:7+3*(104+195)
=2*415-49:7=56:7+3*299
= 830-7=8+897
=823=905

b)155:5+6*(159+78)=7*(29+112)-144:12
=155:5+6*237=7*141-144:12
=31+1422=987-12
=1453=975


c)4*(109+125)-110:20=2*(199+269)-88:8
=4*234-110:20=2*468-88:8
=936-5,5=936-11
=930,5=925
