Question

What is the combined length of all the buttons longer than 1 inch?

Answer 1

Answer:

2 1/2 inches

Explanation:

There are two marks on the line plot above 1 inch; both are on 1 1/4 inches.  This means to find the total length we add together

1 1/4 + 1 1/4

They already have a common denominator; this means we add the whole numbers then add the numerators.

1+1 = 2; 1/4 + 1/4 = 2/4

This gives us 2 2/4.  The fraction will simplify to 1/2; this gives us 2 1/2.

Answer 2

Combined means to add so you are going to add anything over 1 because it says longer than 1

1 1/4  has 2 marks so you add 1 1/4 + 1 1/4 = 
they have like denominators so you can add them together

1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2 

so your answer is 2 1/2
