Question

Calculeaza dupa model:
b) 3 x 24 = 3 x (20+4) = 3 x (10+10+4) = 3 x 10 + 3 x 10 + 3 x 4 = 30 + 30 + 12 = 72

4 x 22=__________________
7 x 23=__________________




Dau coroana 5 Stele si o Multumire ! Daca raspundeti si leu intrebarea asta

c) 5 x 123 = 5x(100+20+3)=5x100+5 x 20 +5 x 3 = 500 + 100 + 15 = 615

4 x 234=_________________
6 x 142=__________________​

Answer 1

Explicație pas cu pas:

c) 4×234=4×(100+20+3)=4×100+4×20+4×3=400+80+12=492

6×142=6×(100+40+2)=6×100+6×40+6×2=600+240+12=852

b) 4×22=4×(20+2)=4×(10+10+2)=4×10+4×10+4×2=40+40+8=88

7×23=7×(20+3)=7×(10+10+3)=7×10+7×10+7×3=70+70+21=161

Sper că te-am ajutat!

Answer 2

Răspuns:

b).▪️4 x 22 = 4 x (20+2) = 4 x (10+10+2) = 4x10 + 4x10 + 4x2 = 40 + 40 + 8 = 88

▪️7 x 23 = 7 x (20+3) = 7 x (10+10+3) = 7x10 + 7x10 + 7x3 = 70 + 70 + 21 = 161

c).▪️4 x 234 = 4 x (200+30+4) = 4x200 + 4x30 + 4x4 = 800+120+16 = 936

▪️6 x 142 = 6 x (100+40+2) = 6x100 + 6x40 +6x2 = 600+240+12 = 852
