Answer: 12.5 hours watching TV

Explanation:

Step 1: We know this is an "in all" question, so we first need to find the fractions to add up.

Each dot on the graph represents 1 of each fraction. For example, the dot above the "1/4" means that 1/4 hours were spent watching TV, and the 3 dots above the 1 means that he watched TV for 1 hour in a row 3 times, so the total number of hours for 1 would be 3x1, or 1+1+1.

So we have:

1/4

1/2

3/4

3/4

3/4

1

1

1

1 1/4

1 1/4

1 1/4

1 1/4

1 1/2

(again, each dot represents 1 of each)

Step : Convert these to decimals so it's easier to add

1/4--> 0.25

1/2--> 0.5

3/4--> 0.75

3/4--> 0.75

3/4--> 0.75

1--> 1

1--> 1

1--> 1

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/4--> 1.25

1 1/2--> 1.5

0.25+0.5+0.75+0.75+0.75+1+1+1+1.25+1.25+1.25+1.25+1.5= 12.5 hours in all

Answer= 12.5 hours

0+(1/4)+(1/2)+(3(3/4))+3+(4(5/4))+(3/2)=12.5

Never say anything is too hard because one day this will be second nature solving these fractions
