Sally either walks, cycles or drives to work. She walks about 15% of the time and drives about 3/5 of the time. What percentage

Ivan

Answer:

25%

Step-by-step explanation:

We need to first convert 3/5th to percentage so we are only dealing with percentage.

3/5 doing division would give us 0.6

Multiply that by 100, we get

0.6 * 100 = 60%

Thus, now we can say:

Walking = 15%

Driving = 60%

The remaining time is cycling. How much?

15 % + 60 % + cycling = 100%

75% + cycling = 100%

Cycling = 100 - 75 = 25%
