Answer 1

Răspuns:

17) a) a×0.25=a÷4

a×1 supra 4 = a÷4supra1

= a supra 4 = a÷4supra1

=a supra 4 = a× 1supra4

a supra 4 = a supra 4

b)

120×0.25=120×25supra100 = 120×1 supra 4=120supra4=30

0.25×3600= 1supra4 × 3600 = 3600supra4=900

4.12×0.25= 412supra100×25supra100

=412supra100×1supra4

=412supra400

9.6×0.25= 96supra10×1supra4=96supra40
