In March Delphine's house had 40% more snowfall than in February. Delphine's house has F centimeters of snowfall in February

Answer: In March Delphine's house has 1.4*F centimeters of snow.

Step-by-step explanation:

We know that in March, the snow was 40% more than in Februray.

First we need to write 40% in decimal form, for this we divide it by 100%

40%/100% = 0.4

Now, in Februray Delphine's house has F centimeters of snow.

If F corresponds to the 100%, 0.4*F corresponds to the 40%

Now, in march we have a 140% of snow, this is:

Snow = F + 0.4*F = 1.4*F

In March Delphine's house has 1.4*F centimeters of snow.

1.4f of 14/10ff

Since 40% of f=0.4f

Then, f0.4f=1.4f
