Answers
Answer:
45/6 - 21/3 =>
Step-by-step explanation:
Take common LCM which is 6
= 45-42/6
= 5/6
= 0.83333333
Conversion a mixed number 4 5/
6
to a improper fraction: 4 5/6 = 4 5/
6
= 4 · 6 + 5/
6
= 24 + 5/
6
= 29/
6
To find a new numerator:
a) Multiply the whole number 4 by the denominator 6. Whole number 4 equally 4 * 6/
6
= 24/
6
b) Add the answer from previous step 24 to the numerator 5. New numerator is 24 + 5 = 29
c) Write a previous answer (new numerator 29) over the denominator 6.
Four and five sixths is twenty-nine sixths
Conversion a mixed number 2 1/
3
to a improper fraction: 2 1/3 = 2 1/
3
= 2 · 3 + 1/
3
= 6 + 1/
3
= 7/

To find a new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/
3
= 6/

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 3.
Two and one third is seven thirds
Subtract: 29/
