Answer:
10.1
Step-by-step explanation:
Conversion a mixed number 4 3/
5
to a improper fraction: 4 3/5 = 4 3/
5
= 4 · 5 + 3/
5
= 20 + 3/
5
= 23/
5
To find a new numerator:
a) Multiply the whole number 4 by the denominator 5. Whole number 4 equally 4 * 5/
5
= 20/
5
b) Add the answer from previous step 20 to the numerator 3. New numerator is 20 + 3 = 23
c) Write a previous answer (new numerator 23) over the denominator 5.
Four and three fifths is twenty-three fifths
Conversion a mixed number 5 1/
2
to a improper fraction: 5 1/2 = 5 1/
2
= 5 · 2 + 1/
2
= 10 + 1/
2
= 11/
2
To find a new numerator:
a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/
2
= 10/
2
b) Add the answer from previous step 10 to the numerator 1. New numerator is 10 + 1 = 11
c) Write a previous answer (new numerator 11) over the denominator 2.
Five and one half is eleven halfs
Add: 23/
5
+ 11/
2
= 23 · 2/
5 · 2
+ 11 · 5/
2 · 5
= 46/
10
+ 55/
10
= 46 + 55/
10
= 10.1
