PRECISO PRA HOJEE!!!​

Answer 1

A- 10x10x10= 1000
7x1000= 7000

10x10x10=1000
3x1000=3000

Sendo assim
7000x3000= 21 000 000

B- 10x10 = 100
7,1x100= 710

10x10= 100
6x100= 600

Sendo assim
710x600 = 426 000

C-10x10=100
3x100=300

10x10=100
100x2=200

Sendo assim
200 : 100 = 2

D-10x10x10= 1000
1000x5 = 5000

10x10= 100
6x100= 600

Sendo assim
5000 : 600 = 8,3333.....

Espero ter ajudado
