Question

Maribel wants to skate 1 1/2 miles on Monday. If she skates 9/10 miles on Monday morning and 8/9of that distance on Monday afternoon will she reach her goal? Please tell me how you got the answer.

Answer 1

Explanation:

Her goal to skate 1½miles on Monday

First in the morning she skate 9/10miles

Then, afternoon she skate 8/9 of the morning distance

Then the distance for the afternoon will be given as

8/9 of 9/10

8/9×9/10=4/5

Then the distance she travelled in the afternoon is 4/5 miles

Total distance traveled is now

(9/10)+(4/5)

LCM of 10 and 5 is 10

(9+8)/10

17/10

1 7/10

Which is 1 whole number 7 over 10

She reached and passed her goal because her goal was 1½ which is 1.5 miles and she later traveled 1.7miles

Answer 2

Yes she will reach her goal

Explanation:

The total miles to be skated by Maribel on monday is 1 1/2 miles.

On Monday morning she skates 9/10miles

If on Monday afternoon she skates 8/9 of that distance on Monday, then she must have skate (8/9 of 9/10) miles in the afternoon which is equivalent to 4/5miles.

Total miles she skated will be 9/10+4/5 = 9+8/10

= 17/10

= 1 7/10 miles

This means that she will reach her goal and even pass the initial total miles she wanted to skate which is 1 1/2miles
