Question

Un tractor ara in 4 zile 49 de hectare.In cite zile tractorul va ara:
a) 73,5 hectare; b) 122,5 hectare?

Answer 1

pai... vine asa:

4 zile ..... 49 hectare.
x zile ...... 73,5 hectare

x = $\frac{4 * 73,5}{49} = \frac{294}{49} = 6$

x = 6 zile .

4 zile...... 49 hectare.
x zile ..... 122,5 hectare

x=$\frac{4*122,5}{49} = \frac{490}{49} = 10$
x = 10 zile.
