I wanted to walk one mile each day in the morning I walked 4/10 if a mile and in the evening I walked 2/5 of a mile what was the total I walked in one day

You walked 8/10 (or 4/5) of a mile.

To find this, you must first make sure both fractions have a common denominator. To do so, multiply 2/5 by 2/2 to get 4/10.

Now, add both fractions. 4/10 + 4/10 = 8/10. To simplify this, simply divide 8/10 by 2/2 to get 4/5.

Thus meaning your answer is 8/10 (or 4/5) of a mile.

I hope this helps!

Probability = 2/21

Step-by-step explanation:

Question is not complete.

To solve this question, the following assumptions are made

1. There are 7 tiles

2. The number representation of the tile is as follows;

5,6,7,8,9,20

a.

Given that there are 7 number of tiles and there are 2 picks without replacement

The probability of choosing a number less than 7 is as follows.

From the given data, number of tiles less than 7 is 5 and 6.

For the first pick, the probability is 2/7

For the second pick, the probability is 2/6

Because there are 6 tiles left after the first pick and there are 2 multiples of 4.

So, the probability is calculated as;

2/7 * 2/6

= 2/7 * ⅓

= 2/21
