Answer:
Twenty-one eighths or 2.625
Step-by-step explanation:
Conversion a mixed number 1 3/
4
to a improper fraction: 1 3/4 = 1 3/
4 = 1 · 4 + 3/
4 = 4 + 3/
4 = 7/
4
To find new numerator:
a) Multiply the whole number 1 by the denominator 4. Whole number 1 equally 1 * 4/
4 = 4/
4
b) Add the answer from previous step 4 to the numerator 3. New numerator is 4 + 3 = 7
c) Write a previous answer (new numerator 7) over the denominator 4.
One and three quarters is seven quarters
Add: 7/
4 + 7/
8 = 7 · 2/
4 · 2 + 7/
8 = 14/
8 + 7/
8 = 14 + 7/
8 = 21/
8
