Question

3 Add: 3 1/3 + 2 1/4​

Answer 1

Answer:

187/12

Step-by-step explanation:

lcm of 3 and 4 is 12

31/3=124/12 21/4=63/12

124+63 = 187

=187/12

Answer 2

Answer:

the answer is 5 7/12

Step-by-step explanation:

Conversion a mixed number 3 1/3

to a improper fraction: 3 1/3 = 3 1/3 = 3 · 3 + 1/3 = 9 + 1/3 = 10/3

To find new numerator:

a) Multiply the whole number 3 by the denominator 3. Whole number 3 equally 3 * 3/3 = 9/3

b) Add the answer from previous step 9 to the numerator 1. New numerator is 9 + 1 = 10

c) Write a previous answer (new numerator 10) over the denominator 3.

Three and one third is ten thirds

Conversion a mixed number 2 1/4

to a improper fraction: 2 1/4 = 2 1/4 = 2 · 4 + 1/4 = 8 + 1/4 = 9/4

To find new numerator:

a) Multiply the whole number 2 by the denominator 4. Whole number 2 equally 2 * 4/4 = 8/4

b) Add the answer from previous step 8 to the numerator 1. New numerator is 8 + 1 = 9

c) Write a previous answer (new numerator 9) over the denominator 4.

Two and one quarter is nine quarters

Add: 10/3 + 9/4 = 10 · 4/3 · 4 + 9 · 3/4 · 3 = 40/12 + 27/12 = 40 + 27/12 = 67/12 = 5 7/12
