1 3/4
To convert a smaller fraction, you can try drawing a picture. In this picture, you can see 1 3/4. - 4
7/4
Now divide the second circle into fourths, and count the total number filled in. You get 7. Now, since each of these 7 is a fourth of the whole, our improper fraction is 7/4. - 5). Once you understand the concept, you're ready to try the math. So let's try a harder one. Let's convert 3 4/5 to an improper fraction.
- 6). You'll start by multiplying your whole number, 3, by the denominator, 5. 3 X 5 = 15
- 7). Now add the number you got (15) to the numerator of the fraction (4). 15+4=19
- 8). Now you'll take your answer (19) and place it over the denominator (5). So our final answer is 3 4/5 = 19/5.
- 9). Congratulations! Now try this one: 2 3/4 = ?
