Question

a)( 2×2,2+1,44:0,3)+1,0(02)= b)0,018:0,9×0,(3)= va rog care stit sa ma ajutati cu explicați ​

Answer 1

a)( 2×2,2+1,44:0,3)+1,0(02)= // transformam in fractii

(2/1×22/10+144/100:3/10)+1 intreg si 2/990=

(44/10+144/100×10/3)+992/990=

(44/10+48/10)+992/990=

92/10+992/990=

9108/990+992/990=10100/990=1010/99=10,(20)

b)0,018:0,9×0,(3)=

18/1000:9/10×3/9=

18/1000×10/9×3/9=

2/100×1/3=2/300=0,00(6)
