Lesson 2 Application Problem
Mr. Hopkins has a 1 meter wire he is using to make clocks. Each fourth meter is marked off with 5 smaller equal lengths. If Mr. Hopkins bends the wire at ¾ meter, what fraction of the marks is that?
Lesson 2 Concept Development
Problem 1
1/3 + 1/3
1 third + 1 third = 2 thirds
Problem 2
3/8 + 3/8 + 1/8
3 eighths + 3 eighths + 1 eighth
Problem 3
6/2 = 2/2 + 2/2 + 2/2 = 1 + 1 + 1 = 3
6 halves = 3 x 2 halves = 3 ones = 3
Problem 4
8/5 = 5/5 + 3/5 = 1 3/5
8 fifths = 5 fifths + 3 fifths = 1 and 3 fifths
Problem 5
7/3 = 6/3 + 1/3 = 2 1/3
7 thirds = 6 thirds + 1 third = 2 and 1 third. Problem 1
1/3 + 1/3
1 third + 1 third = 2 thirds
Problem 2
3/8 + 3/8 + 1/8
3 eighths + 3 eighths + 1 eighth
