2- 1/10=0.1; closest to zero

3- (25-4)/40= 21/40 (common denominator)

4- 12

5- (20-9)/24= 11/24 (common denominator)

6- (6+3/4) + (2+1/2) = 8+5/4= 9+1/4

7- 21+3/4 - 13+1/8 = (21-13)+(6/8-1/8) = 8+5/8

8- 8+5/12 - 5+3/8 = (8-5) + (10/24-9/24) = 3+1/24

9- 20

2.) 5/10 is closest to:  1/5 is equal to 2/10 and 1/2 is equal to 5/10 and that would mean 1/5 would be closer to 0 than 1/2 or 1. So, your right.

3.) 20-21/40 (can't be more than 40 as denomanator)

4.) LCD is 12.

5 and 6 are blurry, you can comment on what they say if you want me to answer. :)

7.) You need to subtract. (c) 8 5/12- 5 3/8 (d)

3 1/24

8.) LCD = 20

I HOPE THIS HELPED.

the average speed of the whole journey is 45 km/h

Step-by-step explanation:

The computation of the average speed of the whole journey is shown below:

Average speed is

= (Speed 1 + speed 2) ÷ 2

= (60 km/h + 30 km/h) ÷ 2

= 90 km/h ÷ 2

= 45 km/h

Hence, the average speed of the whole journey is 45 km/h

We simply ignored the distance as it is not relevant for the given situation

The same would be considered
